Hi Jay, I have added pics to my Google Drive, here is the link - Hopefully works ok. https://drive.google.com/drive/folders/1DTal-_lQXpSz-hBsA4dcv0DcAt4E2wqt?us… A bit of History, I purchased this Amp and Crossover from the USA to replace the missing audio gear as the Jukebox had been butchered and didn't have any audio gear in it. Hopefully those pictures show enough detail?

Wurlitzer 780 noise
by ascott822 19 Mar '23

19 Mar '23

My 780 has began making a terrible clicking/clacking noise as the record comes up. Sometimes it clears up. Recently it continued until the amp fuse blew. Record continues to come up and play but of course no sound. Suggestions as to where the “bug” is? Thanks Sent from the all new AOL app for iOS

AMI Continental 2 Amp R2777B output tube type
by Iain Jamieson 18 Mar '23

18 Mar '23

Hi Everyone, I have an AMI R2777B Basic Amp plus the R2728A power amp. Screened on top of the chassis is 6973 for the output tubes. However, they are not 6973 tube sockets. They are a larger 8 pin socket which looks to be factory installed. Did these amps ever come out with say 6L6 tubes? The wiring on the sockets suggest it may be these as pin 1 and 6 are not connected, but I couldn't find any info to support this. Thanks Iain Pintech Ltd Unit 9, 37 Washbournes Road Wigram Christchurch Ph 0273333716

I have a ton of ERIC reissue 45's from the 80s. They were always well mastered and sound great. More often than not better than "Collectibles" which was their main competitor. My only suggestion is that they really need to publish a list with prices of the NOS titles if they are half way serious about selling them. Even if it's not 100 percent complete or accurate any list is better than no list to help potential customers get started. It's not rocket science.

Ami continental takes record back to the carousel without playing
by Henrik Niinimäki 16 Mar '23

16 Mar '23

Hi, What could be wrong when ami continental II picks up the record on the record plate, but picks it up back 50% of the times, it goes right back to the carousel, and doesn't play it at all. I have adjusted the motor position and miicroswitches correctly. Also replaced the record end microswitch but still doing this? Is it broken micro (number?), or is the new record end switch bad or what else it might be? Transfer relay maybe? Br Henrik

by Flamingo Records 16 Mar '23

16 Mar '23

Hi all, I have a customer who needs the amplifier schematic for a Rock-Ola Regis model 1488 200 play. I don't have any numbers on the amp to refer to. It is a MkII amplifier made for Australia, and has 6BQ5 output tubes. If anybody has this schematic, please let me know. Kind regards, and my thanks in advance, Erwin Boot FLAMINGO RECORDS, HOBART, AUSTRALIA flamrecs(a)bigpond.net.au <mailto:flamrecs@bigpond.net.au> ================================

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
