Hello All,

Haven't had any new transistor radio projects for quite awhile and was surprised when an older radio club friend gave me these two today ! Had called and asked if he wanted a fairly rough, but complete RCA 2-X-62 for free to play with and he gave me these two after I arrived.

Haven't decided yet what to do with them---the outsides of both are rough and dirty with all the exterior metalwork on the Westinghouse badly corroded (including badly rusted screws) along with cracked and chipped plastic cabinet and the back cover of cabinet is off of the 270. Of course, was excited enough when I got home to quickly open them up to see what was inside and found that both were in relatively clean and nice condition internally---the 270 even had its four Raytheon "blue beauties" ! Next step is to see what happens when power applied...

Parts or "patina (clean with corrosion removed)" refurb ???

Pics later...

John

John - You sure are good at acquiring the Bulova 270 with the Raytheon transistors! I still have only found one Bulova 270 and feel fortunate to have it! - Mark

Hello Mark---this is the later 270 which has a PCB and soldered-in Raytheon beauties. The chassis appears to be in nice original condition. Since these are known to be mediocre performers, am considering just testing it by carefully bridging electrolytics using clip-leads to satisfy my curiousity and then leaving it alone as an item for trade since it's a desirable set to some. Would like to keep the transistors for my 8TP-4, but it's now too nice (even with remaining cosmetic issues after careful cleaning) to even think of parting it out...

Decided to go ahead, disassemble, and start cleaning so that they could be brought into the house and ended up spending the rest of the day on these---just couldn't leave 'em alone in that state ! The aluminum trim on the Westinghouse was so badly corroded that some of it had been eaten away. It had been so well used that the "kickstand" had wallered out the holes in cabinet and had actually worn into the plastic on sides ! And the volume knob was so encrusted with crud that it appeared black. Took a lot of effort with Scotchbrite and soapy water to remove all the "corrosion crust" from stand. Hours of cleaning on both ! The 270 cabinet and knobs actually cleaned up much better than I thought they would.

Applied power and the Westinghouse actually picked up a couple strong locals at low volume. The felt voice-coil dust-cover had been partially eaten by bugs and debris had entered causing distortion---very carefully removed the loose fragments of felt and vacuumed out the cavity. The 270 only had some "scratch" when tuning at max volume...

Decided to stop for evening and get back on track with nightly routine. Will post progress when able...

Todays pics...

John

Hi John - I also have a Bulova 270 with the printed circuit board, but it doesn't use the blue Raytheon transistors. I've thought of removing the Raytheon transistors from other radios and putting them in one of my 8TP missing most of the original transistors, but decided it was better to just buy the Raytheon transistors instead. - Mark

I'm sure they'll look like new when you've finished working your magic.

Thanks Guys !

Got up early this morning and worked on these before going out to garage...

Used mini-clip leads to bridge the two audio caps on the 270 and it worked well without any adjustments picking up several local stations---those blue Raytheon beauties are working fine ! Decided not to detail-clean, replace electrolytics or do any more to PCB since I plan to sell this one. Did carefully clean cabinet and knobs and they turned out pretty good, though cabinet and right side of grille has noticeable wear and the back cover is off.

The Raytheon blue oval numbers are: CK760A (7-08), CK766 (7-07), 2N132 (7-08), 2N138A (7-08). Am guessing that the date codes indicate the 7th & 8th week of 1957...

Replaced the three electrolytics in Westinghouse and it sounds very good considering the debris I removed from voice-coil cavity. Not as sensitive as my other set, but couldn't adjust the 3rd IFT since core was tight and don't have the proper square-tipped alignment tool. The ANT trimmer screw had to be nearly all the way out to peak, so am wondering if there's another problem. Also strange was that the low-end of dial was more sensitive than high---first time I've ever seen that in any radio I've worked on !

Pics thus far---270 complete, Westy requires a bit more TLC...

John

Got these two completed today...

Even though I plan to sell the Bulova 270 with those four blue Raytheon beauties before I get too attached to it, went ahead and replaced the five electrolytics keeping originals as usual for future owner. The tuning cap was a little "scratchy" all through its range, so applied a tiny drop of DeOxit Gold liquid to rotor contact point and its now noise-free. Also needed a couple small squirts of DeOxit Faderlube to eliminate volume control "crackle". Radio now works and performs decently for a set with only one IF amplifier stage.

Spent over an hour carefully polishing the Westy tuning knob and brass bright---turned out pretty well considering condition. The bright silver disk beneath is actually paper with foil laminated on both sides---thought it was just a polished aluminum disk until corroded edges broke down during cleaning. Also attempted to aggressively polish the aluminum trim at bottom, but it was too badly damaged by corrosion. Did polish the two areas of plastic on each side with Novus-2 to see if it would shine and it did---maybe do entire radio one day, though with cracks and chips don't know if I want to waste that much more time on it...

Decided to play with Westy alignment the other day after noticing that the dial calibration was quite a bit off. Centered the 1240 Conelrad symbol with lower dial indicator and used distant oldies station on that frequency as alignment source. After adjusting OSC trimmer to bring station in to that point, the ANT trimmer now peaked normally and radio performance MUCH better. Am also still amazed about how good this set sounds !

That came out very nice. Is it 6 transistors or 7 transistors? I've got one complete with the original moldy display box from eBay, I think a 6 transistor set. I haven't even opened the package yet and it was sent 3 years ago!

Thanks Metzman,

The Bulova is four transistor and the Westinghouse is seven.

Remember you kidding me about moving so fast on my projects, but can't imagine having anything sit around that long without even being opened and examined !

I've been getting sidetracked by a passion of my youth lately. Building models! Amt is rereleasing all these old kits . Right now I'm working on the 57 Chevy "pepper shaker" 409.

Hey Metzman---I built a lot of AMT & Revell model cars as kid back in late '60's to 1970 when electronics and radio really took hold. Still have several... Might even have that "Pepper Shaker" on an unused sheet of decals ! Most were Tri-Five Chevys... Found this sad 50+ year-old model of a '57 Nomad in a childhood "junk box" recently...

I'd hang onto it! Vintage styrene is becoming more sought after these days. I know this is going off topic so I will leave it at that.

Naww, let's continue the H/J; John don't mind. :wink:

I built these around '59-'60. The '64 Galaxy of course in '64. The AMT is still in the box, virgin.

Nice collection of old models, Richard !

Remember---most have radios (at least molded into dash !)...

Really liked the '64 Galaxie 500's---especially the XL...

Embarrassed to say that I left my models white (or original molded color) as I didn't have the patience to paint them---except for a hot-rod built out of scrap parts that I wasn't worried about ruining (and it turned out pretty well !)...

Sold the Bulova quickly to a guy in Torrance, CA---it's now in the USPS "pipeline"...

Yeah, I loved the Galaxy XL fastback, with it's console and bucket seats. Unfortunately well beyond my financial ability at the time. The model of it was more in my price range, LOL! I don't remember their pricing, but do remember looking at new '65 Galaxy's at a dealership; over 5 grand, for a Ford! Couldn't believe my eyes.
