RESTORATION TOPICSThe 1928 Brunswick Model 5NOBY DIC K PARKSThe Brunswick Model 5NO,also knownastheRadiola 60,hasbeen described as"the firsttruly modern superhetdesign:one-dial tuning.AC tubes, chassis construction, and wire antenna instead of the bulkyloop," asused inearlierRadiolas.* In 1928 itsold for 175 (later 147) without any tubes.A set of radiotrons for this would set youback 27.50 per,for atotal of 202.50 (that's 2,684 in2012 money!). Let's see what thatmoney boughtway back then.Figure 1shows aBrunswick model 5NO,aninetube table model superhet with an IFof 180 kHz. Ituses six 27 triodes forthe RF,oscillator and IF stages, plus another 27 forthepowerdetector,aswellas a71A intheoutput stage.The rectifier isan 80 on aseparatechassis,and ithas acovered terminal strip forconnectionstothe RFchassis.Ifound my 5NO on Craigslist and drove60 miles topick itup—since itweighs ards isthrough the removable back panel.When Igot iton the bench, Ipulled out bothchasses and cleaned ofal the dust and dirtofthe ages, thankfully noting that the radio hadneverbeen modified inany way that Icould see.*Alan Douglas, Radio Manufacturers ofthe/920's,VolumeI,p.45Starting with the power supply, Imade resistance checks to see ifal the transformerand choke windings had continuity. In 1928,paperfiltercapsweretherule,and Icould findno evidence of leakage, so the bench Variaccame into play. Ipulled the rectifier tube atfirst to avoid any DC overvoltage, as therewas noload asyet.Otherthan anopen powerswitch, Ifound noproblemsand connected anHV bench supply totheB feedpoint,runningitsoutput voltage up to 250 slowly, lookingfor sparks or smoke.

There wereno fixes needed toput this radio up and running,otherthan protecting afew frayed wireswith short lengthsofheatshrink tubing.The cabinet did need some work, though.This Brunswick had the beginningsofveneerdetachment,butthatwas soon putright. Backwhen Iwas anewbie, acouple of nice thickcoatsofpolyurethane pleased me noend,giving anice shiny hard finish. The mandarinsof the hobby currently frown on that sort ofthing,however,so nowadays my radios get alighttreatmentwith scratch sticksand tung oilvarnish, and not much ofthat, either.

This past March, members of the NewJersey Antique Radio Club had theprivilege oftouring the Alpine, New Jersey,radio towerfacility that was built by FM radiopioneer MajorEdwin Howard Armstrong.The Alpine tower(also known asthe Armstrong tower) islocated on 15 acres on theHudson River Palisades north of New YorkCity.Construction wasstarted in1937 byArmstrong as alocation toconduct his FM radioexperimentsafterhe was forced toremove hisequipment from the Empire State Building. Itwas finished in1938.The first FM transmitter,W2XMN,operated from hereat afrequency of42.8 MHz with 40 kW of power. The signalscould beheard approximately 100 rong had worked with RCA developingthe FM system, but ties were severed whenRCA realized that FM would be aseriouscompetitor tothe established AM broadcasting signals that RCA supported. Armstronghad made headlines when, inJune 1936, hegave apresentation fortheFederalCommunicationsCommission,impressing the audiencewith thefidelity and static free signalsthat FMcould deliver. RCA retaliated and lobbied theFCC tochange vthe FM band, then covering42 MHz-50 MHz. to88 MHz108 MHz by1945.This rendered al oftheold FM receivers useless. RCA also claimed the patents onArare REL receiver and speaker.theinvention of FM and tied upArmstrong formany years inlitigation. Armstrong committed suicide in 1954, but his heirs eventuallywon theirlawsuitsagainst RCA.Though lacking public recognition during his lifetime.Armstrong was apreeminentforce inthedevelopmentof FM broadcasting.His many awards, acheivements, and honorsincluded:IEEE MedalofHonor —1917French GovernmentLegion ofHonor —1919Franklin Medal —1941AIEE Edison Medal —1942National InventorsHallofFame — 1980U.S. Postage Stamp — 198342 PatentsDuring World War Ithe site was used asaradar facility, but was turned of following Armstrong's death. Columbia Universitymaintained thesite until itwassold inthelate1960s. Today the tower facility isowned bythe Alpine Tower Company, aprivately heldconcern,and isused forcellularantennasandsome local television and radio stations.The tower entered broadcasting historyasecond time after the events of September1, 2001. When the World Trade Center wasattacked, local television stations lost theirtransmitters.

Even whennothing else remainsofsetthey wereonce theheart of, we know that they're likely still capable of adeep,rich sound.Thereisasolutiontothis quandry,and while itdoes not qualifyascollecting,itis anice way toputthatchassistogood use once more.The idea, ofcourse, istosimply take thatold chassis (put back into perfect workingorder, made safe, and with fuses properly installed), pair itwith awell-matched speaker,and then custom-build a small cabinet tohouse thespeaker,loop antenna,dipole antenna,and chassis. This technique isnot exactlyoriginal,and Ihave seen many examplesofitatswap meets overthe years, but itdeservesour renewed consideration.After al,originalpartsare hard tocome byand today'semphasis ison recycling,sowhy notapply this concepttoradio?The cabinet you fashion can be as simpleorasfancy asdesired,and can be made fromhigh-end store-bought lumber orfrom scrapsfrom your garage. Itcan be stained and varnished for anatural wood finish,orbepaintedinattractive colors. It's al about creativity.Hopefully, you've salvaged some old knobs,butifneeded you can usegeneric ones.Would your new set be stereo? No, but itsurely would be high fidelity ifitwas basedon agood chassis well matched tothe speaker. There were many types ofgood sets (using apower transformer and 6.3-volt tubes)that had AM/FM and push-pull output circuitry. For instance, Airline (often using aWells-Gardner chassis), Silvertone, Zenith,and RCA made sets that would be ideal forthis type ofproject.Obviously,the largerthe chassis,the lesscompact the final set will be. Most chassisrequire 3.2 ohms of load impedance, so Ihave found that oval 4-ohm automobile radio or German table set speakers work extremely well forthis purpose.They take upless space inside the cabinet and thus allow10

RADIO M E MO RIESAn RCA 9K2 Is Once AgainPart of the Fa milyB Y RI C H A R D B R E WS T E RRichard BrewsterRCA 91C2 beautifully set of byhisdaughters. Meghan. Rebecca,and Emily.12

eof my earliest childhood memorieswas listening toour"hand-me-down"RCA 9K2.The set wasoriginally purchased by my uncle inthe late 1930sand wasacquired by my family when my uncle got anewerset.Iwas always alistener, and was especially fond of kids' after-school programs.On weekdays Iwould tune in at 4:45 tohear Dick Tracy followed by Terry andthe Pirates, on to Jack Armstrong, the AllAmerican Boy, continuing with Sky Kingand ending with Tennessee Jed. On Saturday mornings Iwould eagerly tune toLet'sPretend and move right on to Grand Central Station. Sunday mornings would bringthe Comic Weekly Man, who would read thenewspaper captions of some comic strips.And,ofcourse,Sunday afternoon at 5wouldbe The Shadow. Inever missed that. Certainevenings would find the family listening toMr. Keen, Tracer of Lost Persons or OurMissBrooks,orperhaps my father's favoriteprogram,Gang Busters. Ieven enjoyed some"ladies' shows." Before school Iliked tolisten to Missus Goes A-Shopping, and uponcoming home for lunch, Iwould tune in MaPerkinsand Our GalSunday.But my earliest memories are of "Beautiful Dreamer,"Arthur Godfrey's intro on his 6a.m. show. Iwould listen while lying on theliving room sofa, as my mom got dad oftowork. Inthose early days, Ilistened toeverything:bigbands,quiz shows,soap operas,youname it. Well, almost everything, because Ihated the news. Boring! Iremember askingmy mother, "When the war isover,will therebe no more news?" Obviously, the news wasalmostexclusively aboutthewar.Yes, itwas areal treat when the 9K2showed up.Afteral,ithad shortwave bands!My brothersand 1would listen forhourstothestrange noises,weird music,and foreign voiceson the short wave bands.The 9K2 coveredupto60 MHz and even had along wave band!Itwas very sensitive with atuned RF stage,separate oscillator,and mixer; RCA called thetuning unit "Magic Brain." The audio consistedof a6L6 driving a12inch speaker.As Igrew older, Ibecame fascinated withthe insidesofradiosaswell,soofcourse that9K2 had tobe taken apart! My brothersand Iwould routinely head forthe localtrash dump,and Iwould always find some old radios tobring home todisassemble. To my mother'sconsternation, my dresser drawer was filledwith radio partsinstead ofclothes.Partsofthe9K2 went into thatcollection.Fast forward tothe 1980s. Ihave acquiredafamily ofmy own, but Inever lost my appreciation for old radios. One day Iwoke upthinking that Ineeded toget another9K2,soIplaced an ad inAntique Radio Classified forone and hoped. Now bearinmind thatA.R.C.is anational publication, and the 9K2 isalarge console set.
