Bench Test AMI Conti Mono Amplifier?
by M De Simone 10 Mar '23

10 Mar '23

Greetings, another amp testing question. With the help of Rob I was able to bench test the last amp I worked on but now would like to bench test a Continental mono amp. I know it can be done as I saw it on YT but they never mentioned the setup. I’m hoping to learn which wires or contacts I have to jump to play it on the bench? Thanks, Mauro Sent from my iPhone

Rockola SS amplifier FET Identification
by M De Simone 03 Mar '23

03 Mar '23

A fellow jukebox repairman asked me if I knew of a substitute for this FET transistor. I do not, since I work predominantly on tube amplifiers. So I thought I’d ask the group here and see if I could help him out. It is Q18 on the “mute and squelch board” and Rockola part # 52342 and the part description is: N - Channel Junction FET. I hope that’s enough information as I don’t yet have a model number. If anyone might have a cross reference number that could be used here that would be great. Thanks, Mauro Sent from my iPhone

Resending because it may not have been seen correctly by all, and the link to eBay is fixed. Thank you John & Peter, When I searched the archives here previously for info West-Tech’s name came up, but most mentions stated that the main guy Gib had retired. I will reach out to them but has anyone had recent work from them? Any thoughts on the “Goldhead”?

There was also a Thorpe Cartridge you might check all the Suppliers for needles and Cartridges.

Weird Question
by Jamie McElroy 02 Mar '23

02 Mar '23

Hello all, I'm still a bit of a novice but have been fortunate enough to have restored an AMI G-80 and F-80, so relatively the same in most respects but I'm learning. So here is my question. Is it possible to change the speed of the turntable motor on a AMI D-40 Jukebox from 78rm to 33rpms? I don't know if that's possible. Does anyone have any thoughts? I was hoping to restore my D-40 and play 10 inch 33 Lps on it. Please let me know if I'm just crazy or this a possibility? Thank you as always. Jamie

Seeburg Wall Box 3W1
by johngartman＠charter.net 28 Feb '23

Gentlemen, I have been on this list for a long long time, have 4 jukeboxes AMI-C, Wurlitzer 2700, and a Seeburg HF100R and an M100A. I have just picked up a 3W1 to hopefully hook up to my HF100R. Looking it over it looks like it only needs the glass dome and coin glass. Ordered from Victory Glass. I do not know much about Wall Boxes yet there is some information in my HF100R Manual. Some Questions for the Group. Looking for Gasket for the dome glass I see a set for sale for the 3WA 200 selection are they the same? I am a little confused on a Stepper? Or is that a Wurlitzer thing? Does the 3W1 just plug in to the selection receiver? I will get into the manual as soon as I have a little more time. Thanks for any help or advice you can share.

Testing a W1500 amplifier with a newer mechanism?
by M De Simone 28 Feb '23

28 Feb '23

Here’s a fun one! I have need to test a Wurlitzer 516 amplifier from a model 1500 but the jukebox is 2 hours away. I have a mech from a 1700 or 1800 set up that I use for testing amplifiers from about models 1800 to 2300. The 516 amplifier uses an 11 pin plug to the amplifier as does say, the 530 amplifier from a model 1900 but when I compare the schematics they appear very different. Would anyone know if I can test this amp with this mech? I do realize the 1500 uses a field coil speaker and I have an adapter for this purpose. I just don’t want to smoke any components and am concerned. Thanks, Mauro Sent from my crowded garage/shop
