Update to Seeburg TSU5 Blowing Cap Issue
by Jerold Kress 17 Jan '23

17 Jan '23

I found no shorts to ground that aren't supposed to be grounded, both with tubes & pulse amp in and out. All electrolytics are in the correct configuration. Questions: can I power up the TSU5 without C514 to test if any AC voltage is reaching it? Can I power up the TSU without the other juke connectors plugged into it? Hoping to obtain a new 6X4 & C514 cap today for retesting. Any suggestions or comments greatly appreciated. Here's a link to photos of the wiring with C514 currently removed. https://photos.app.goo.gl/5Bp27qTEeipyfni28

AMI Continental 2 Microtecnica bias spring
by Federico Croci 17 Jan '23

17 Jan '23

Hello everyone! I'm working on a Conti2, italian Microtecnica version. I installed a new Audio Technica Stilo (Atn3600l), but I still have some trouble playing some 45s, towards the end of the records, when the tone arm begins to push on the switch for the end of the record. The reset microswitch it's the original one, maybe it could be changed with some other model...? Also, the Microtecnica version it's missing the bias spring I can see in the Conti2 manual. Just wondering if someone has a full kit to sell (I'm missing everything, the orange metal support part, as well as the spring itself), or if it can be bought somewhere. Thanks! -- Federico Croci wiz(a)tilt.it www.tilt.it

seeburg hf100r motor noise
by Lore Gianno 16 Jan '23

16 Jan '23

Hello, I own a working seeburg 100R. I have always used it as it is (I seldom use it) but now I'm trying to fix all the things that are not really well tuned. One thing is that playing side A of a disc the mech-motor is really quite, while playing side B from the motor-gears "area" there is much more noise. I tried to understand where the noise exactly comes from but it is quite impossible to understand. As you will see the noise is generated only after a disc of side B is put into play position. I uploaded a video, maybe gives some clues to experienced people like you in order to bring me some goos suggestions! Here the video link: https://youtube.com/shorts/hZVCpzK66gs?feature=share Thanks in advance Lore

FOLLOW UP TO SEEBURG TSU5 ISSUE
by Jerold Kress 15 Jan '23

15 Jan '23

It was suggested I test DC voltages to both C514 & 515 as well as pull the 6X4 and test the AC coming in. 80VDC on C514. 69VDC on C515. C514 was heating up with these tests so I switched off the machine as soon as I could read the voltage. With the 6X4 pulled I next tested 313VAC coming from the transformer to pin 7 of the 6X4 socket but then something unexpected happened: C514 blew. There should have been no voltage reaching either cap with the tube pulled. This suggests a short somewhere but I can't visually see any short. How else would voltage reach the caps? I'm replacing both caps & getting a new 6X4 next week but I don't see this solving the problem if the cap blows with the tube out. Any ideas or suggestions welcomed. jerold k

FOLLOW UP TO SEEBURG TSU5 ISSUE
by Jerold Kress 15 Jan '23

15 Jan '23

This is a follow up to my previous posting about issues with my Seeburg TSU5. I've isolated the problem to C514 over heating but so far have not determined the cause. I replaced C514 & C515 and R518 that bridges their negative ends. (I tested the caps to be sure they weren't shorted & the resistor's value is good.) C514 is connected to the -400V side of the 6X4 rectifier tube. I know this is a positive ground system so I was careful to replace the caps in their proper configuration, with both pos ends soldered to ground. I've switched out the 6X4 with 3 working replacements (all from working guitar amps) but C514 continues to overheat. (I shut down the system after a few seconds but in that time C514 is warm to hot.) I can test the voltage reaching this cap if that info will help in a diagnosis. Any insight into why this cap is overheating so quickly would be appreciated. Thanks! jerold k

Wurlitzer 3300 Low Volume
by Donald Whiting 14 Jan '23

14 Jan '23

I would appreciate any help with this. I’m not that familiar with Wurlitzers mostly work on Seeburg I have a customer that’s and older gentleman that said the needle broke and he replaced it on his Wurlitzer 3300. Since then it has low volume. I stopped by to take a look and he had several new needles. So I replaced it still low volume. Should I replace the cart at this point? The needles are the correct ones. He said it has been working fine for the past 20 years Thanks Don

Mills Constellation Amp I have this amp taking up shelf space. Anyone have a need/want? Email me or post here with what you think it's worth/what you will pay/or who might want to buy it. I've never attempted to power it up. I've never touched a Constellation. It came with some other parts I bought some time ago.

Input transformer for Wurlitzer 771 Amp from 416-616
by M De Simone 08 Jan '23

08 Jan '23

Well this is new for me, although I’m getting pretty good at selecting replacement output transformers, input transformers are out of my comfort zone. I need help in selecting an input transformer for this amp and was hoping Jay or another kind member could suggest one that would be a good fit. I prefer Hammond brand as they are easy to get here in Canada but am open to other suggestions. Here is the page I found but prefer a recommendation. https://www.hammfg.com/electronics/transformers/audio/124 Thanks, Mauro Sent from my garage.
