Victor Electrola 12-15

I need pictures of the inside of this electrola i picked up a very nice case ,have the amp
tone arm speaker etc but pictures would be a big help thanks Don

Check your PM for information regarding pictures of this machine. I turned the house upside down & found wiring diagrams for the 12-15E sent to me by Electrofreak back when I bought my machine. I don't know if you need these pages, but then again they are quite useful. So, here they are:










On previewing the page, I did notice that the pages are hard to read, if you want PM your address & I'll mail you a copy of each page.

The above pictures are my posts, and the scribbling on the schematic is mine.

Now, just what will you be wanting? Do you want a picture of the back of the phonograph, open, and showing the amplifier and speaker placement? I can take a picture of about any part of it that you want.

Since you've posted the same questions in another message board, is Mark Lynch going to help you?

At present, I'm making my recently acquired 12-25 ready for getting together, but it bears no resemblence at all, to the 12-15. I expect it'll sound about the same.

I have the Brunswick equivalent of the Victor 12-15 (their P-11), and it sounds just phenominal. The 12-15 does, also.

Electrofreak,
Your expertise will help kick the project into high gear! I sold my machine to Mark Lynch & he is helping Panatrope too. I sent a copy of your wiring diagrams to Mark as well. Both Mark & Panatrope do know that the notations are your work. I want to thank you for your previous assistance when I had this machine but due to a change in circumstances I ended up selling this particular machine.

You might also want to give John (aka, "Orthophonic") a shout on this one too. He might have the actually service documents on this particular machine.

I have the original schematics and they are the same as the first picture in the posting. The second has resistors of ~47K across the 4MFD filter capacitors to bleed off voltage when the unit is shut down; these are a good idea! Originally voltage could remain after the unit was shut off and could cause some really nasty electrical shocks!!! The half wave UX281 rectifiers will be extremely hard to locate and they can be replaced by mounting a NTE or ECG 125 diode on the proper pins of the tube base that you would use in series with a load resistor. The value of this would have to be figured out; another way would be to mount a type 80 or equivalent and run wires to the appropriate tube sockets but this is not really a good idea. The diode/resistor method is best; the resistor is chosen on the basis of the current draw required and the voltage drop needed to drop the voltage to be the same as if the original tubes were in place. There is no need to connect anything to the original transformer leads that used to light the rectifier tube filaments; the result will be less load on the power transformer and it will run cooler and use less current. The 199 and 210 are triode amplifier tubes; the 210 handles a little more power and both are a vast improvement on the older WD11 tubes. All of the 99 types are identical whether it is a 99, 199, 299, 399, or such; the first number referred to the compant that made the tube. These are much more available but if they cannot be found, the base can be removed from a burned out tube; the glass exhaust tip broken off from the glass envelope inside and a subminiature 5676 tube and resistor can be placed inside and the resulting affair will appear and perform much like the original. I have several hundred of these, I think. If I can help, pleas let me know but it may take time as I am in the middle of paper writing for classes :-(

Hello 3 Vics. Hope you are doing okay. Welcome back. Email me when you get a chance.

And another hello for 3Vics! Welcome back!

ORTHO:

I haven't the Victor notes in front of me, but it's also possible to calculate the necessaty resistor to shunt the X99 filament section of the big divider resistor, so that the voltage amp tube can be changed to a 30. I seem to feel that 30's are still to be had a lot easier than the X99's. I've known of them being used in place of the X99 (I naver have yet), and they worked very well.

While the miniature battery tubes will probably do a good job, and maybe even better than the X99, I just have a revulsion to seeing a 7 pin miniature in a Tomcat amplifier!![B]

Good to hear from you, Electrofreak! You actually do not see the subminiatures; they are inside the burned out 99 tubes. I have a number 0f 30's so that is not a problem, either :-)

3 Victrolas sent me copies of your notes Doug and Mark sent the manual also
i picked up the cabinet just to save it from becoming a curio cabinet !! i have the amp speaker and tone arm etc in my spare parts ...but there are other thing missing still
I was looking to add another early electrola to go with my 12-25
