RCA 67V1 & Philco 42-1008 code122

Forum,
Found these 2 nice consoles at a local garage sale today. Wood still nice, but needs attention. Philco missing the record player though. No missing tubes. Loaded them both (Philco$40; RCA $20) Did I get taken on the price?

Marv, I think you did pretty good!

Stein lists the Philco's value at $175. 9 tubes, 3 bands, with record player (which you're missing).

Stein doesn't list the RCA, but Slusser lists a post-war model 67AV1 at $75-85. Is this your model? Console-R/P, 1946, right til-out drawer, left lift top, inner phono, 4 knobs, BC, SW, 7 tubes.

But after you get them fixed up, what are you going to do with them?

Doug,
The RCA is as you described, and the pix under resources for the 67V1 are identical to mine. The tag is actually torn off, but was able to see the 67 and next letter (partially missing)looked like the left side of "V". So I went from there to resources. The inside rear of the cabinet next to the rotating antenna has a stamp that reads July 23, 1947, certainly post war. Any ideas for the Philco phono and cost? I'll try to find a local buyer or just store them with my other radios in a spare bedroom. Ebay is an option, but shipping consoles, the attendent concern of cost, and safe arrival overwhelm me, especially UPS. I've had poor results with them if the package is more than just a 2 lb hand full. Just finished 2 flat carts with casters to move them around the shop. They're too damn heavy for this 67 year old to be lifting around.

Doug,
Finally opened the RCA, since just having done the 16T2, and they're similar except the 67V1 doesn't have an RF stage, but has 6K6 PP output. Its been recapped with a lot of orange drops and the 3 section can replaced. The double tapped vol. control replaced with a non tapped part, but with a plethora of extra outboard resistors. Haven't analyzed the add-ons to decide if it actually does the same job as the tapped part. The transformer was replaced (a real hack job) overhangs the chassis about 1 1/2 inches, but the filament string is connected to 1 side and the CT of the winding, for what I'd guess is 3.15VAC. Would this set have ever played again wired this way?

The outboard resistors calculate and measure very close to schematic value of the original double tapped pot. Several other components are different values than stated on the schematic, and the wiring to the phase inverter and detector are switched, based on the tube layout diagram.

Doug,
Here's a real poser for you. Since a large power transformer that overhangs the chassis was added, I'm trying to come up with specs for one that'll fit. The documents for the RCA 67V1 quote plate currents for all the tubes individually, including the 5Y3 rectifier. If I add them, I get 138 ma, but wait the current quoted for the 5Y3 is exactly the plate current for the other tubes, so current rating for the transformer should be what is actually used plus any losses. Is there a crude rule of thumb for rating the net current requirements for the transformer?

Hi

Don't count plate current of your 5Y3. It's actually in series with everything else. Looks like 69 ma for B+ current.

Transformers are rated without any margin. A 70 ma high voltage current transformer was popular.

The duration and magnitude of the initial surge isn't long enough to damage the xfmr. For peace of mind, add a CL-90 inrush limiter, available from Mouser. It'll save wear and tear on the tubes, maybe the xfmr a little.

The initial surge might be several times the radio's steady-state amps? If you were to rate the xfmr for the surge amps, it would be too large, physically - and too expensive.

Doug/Norm,
TRANSFORMER PROBLEM SOLVED. After searching hi an lo for an exact/close match for original transformer, and had a list of 18 from PTOP, but couldn't confirm any would fit thru the chassis like before. The big Triad R16A that came with it was plenty powerful (700v CT @160ma), tested good, but just didn't seem to fit the spot. It is an upright and mounted that way, but being just a little smarter than the average bear, took the case off, made small mods to the chassis cut-out, set it in horizontal allowing clearance for 2 tubes and filter cap, marked 4 holes, drilled/tapped them. Mounts perfect, with wire egress under the chassis as before, and barely overhangs (1/16 inch) the edges. I did confirm that the last rebuilder had the 6.3V filaments connected to 1 side and the center tap, which is half of what should have been. OOPS! Sorry, almost broke my arm giving myself a pat on the back. Based on the amount of iron and rating of the Triad, I suspect it'll last a lot longer than the original. It was a good day here for old radios, and Thanks for the help.

That's the way. Now that original parts aren't available we have find other ways. Good thinking on remounting the transformer.

Hi Marv

I usually list two sources from the AES catalog. West-Tech Services 304-349-2149 or www.west-techservices.com . The other Vintage Electronics 601-264-4755 or phonoed@aol.com .

:Hi Marv,
Your record changer is a Crescent 200 series covered by Changer Vol 1 Sec 10 or SAMS 9-27. You might want to check Garage cartridges/needles or something like that name, easy to find with search. The number you have is a valid cartridge number for that changer. Appears you have original stuff. Those cartridges can be rebuilt. Fellow over on ARF does it and also has a do-it-yourself site page.

Bill,
Thanks lots. I was overwhelmed by all the subject matter. Almost fell asleep trying to read all the material and strings. WOW!! Old radio is not dead, but maybe I'm trying to cover too much ground in "one fell swoop" to use an old cliche. Waiting on stock availability from PTOP, decided to dive into the phono just to keep busy, but I think I'll be a while on the electronics in this set, then on to the cabinet restoration.

Norm,
I read the article by Larry Weide about the old dial bezels, plating, coloring etc, under the reference articles heading. The one on this RCA 67V1 is a stamped piece of solid brass, not so intricate, but never the less unique, and appears to have had polished brass as well as copper plating or Rose over polished brass. I can't find a good color picture of this bezel anywhere on the web, in order to duplicate the original appearance. Is Larry a regular contributor to this forum?
