Does anyone out there have the schematics for the P12 model 550 jukebox amp. I am having a difficult time finding them. Or a photo of the bottom of a working 550 tube amp. I need to see how the cartridge input is wired after the volume control box. Specifically between the phono input terminals, fir...

Hey guys. Does anyone have photos of the inside of the Wurlitzer 550 tube amplifier they can share? This is the amp that pairs with the Wurlitzer P12 jukebox. I need photos of the inside because someone added an internal low pass filter that I would like to remove but I can't tell what has been modi...

Final update. First of all, thanks again for all of the great feedback and suggestions. I have Solved the high frequency problem. I removed the volume control box and clipped the low pass filter (cap and resistor) that was wired inline from the input to ground. Immediately the bass and mid tones ope...

Thanks for all of the replies. All great information. One thing I should probably clarify, the sound is actually very good other than the exaggerated treble. I bought a few different caps the other day (waiting for delivery). Thank you Matt Tech! I chose a 220pf, 470pf, and something in the middle. ...

Thanks Rob! This is good info. Victory Glass sold me a Pfanstiehl P51-3. I also picked up the suggested volume box conversion kit that I would assume addresses any compatibility issues… I may have assumed wrong. So my cartridge is ceramic… "The first two are ceramic and require an input impedan...

Thanks Ron. Do you think the needle pressure has anything to do with this high end distortion? Or should I focus on adding a capacitor to filter out some of this treble?

Thanks.

Matt, thanks for your reply. How do I check the needle pressure?

Hello, I recently upgraded my Wurlitzer 412 tonearm with a modern 78rpm cartridge from Victory Glass. It was a fairly cheap unit at around $20. Right away I noticed that the treble was very pronounced with almost no bass. I checked the crossover position on the 660 amp and moved it from high to mid....

Hello,

I am looking for a Wurlitzer 412 credit accumulator cover. Do you still have one available for sale? Also looking for the bottom (larger) old drip pan.

Thanks!

Thanks Craig. I will pick up a copy of the manual, but that sounds like a good place to start. BTW, have you heard of anyone using a P12 tone arm on the 412? Mine seems to work fine but it took a few destroyed records to figure out that I needed to rotate the needle about 20 degrees to the left. -Tony

Hello everyone. New member, first post, first jukebox purchased last month. I am an avid radio, telephone, and just about anything else mechanical collector! I am very excited about my new purchase. Any tips on maintenance, oil type (where to buy), how often oil/lubricant is needed, where to add gre...

Are any of these parts still available?

I need:

-Cover for the credit accumulator
- Rear (larger) oil drip pan
-wood baffle for the back of the speaker enclosure (hole cut for speaker magnet)
-back door


Thanks!

-Tony
