Seeburg HFMA1 amplifier Crackles
by M De Simone 22 Jun '26

22 Jun '26

I have an HFMA1 amplifier that has just been completely rebuilt, all caps changed and resistors checked. Tubes are all verified good. Problem: As I slowly bring up voltage I start to hear the signal but if I bring it up any more than about 70-80 volts on the mains it begins to make a crackling sound and the current runs away. I have it connected to an amp meter and shut it down when it starts quickly climbing past 2 amps and crackling. Now, through troubleshooting I have found that it still happens with only the 5U4 installed in the amp. I’m thinking it has to be one of the transformers breaking down at higher voltages BUT I am getting proper voltages from the power transformer and preliminary primary resistance measurements indicated the output transformer is not shorted. Need some opinions from the wisdom in this group. Any thoughts on which it might be or perhaps some other opinions? Thanks as always, Mauro Mississauga, Ontario, Canada Sent from my iPhone

AMI Conti 2 transporting
by Andrew Burkhart 22 Jun '26

I am about to pickup a Conti 2 and bring it home. What is the best way to transport this unit? It’s about an hour drive to the machine. I’ve transported early 60’s Rockola’s by removing records & turntable, strapping tone arm and anything else that could fly open or move and laying it on its back in a large SUV with success. I’m worried this might not be sufficient for the Conti. Thinking of renting a U-Haul and strapping it to the wall. Also heard of the title strip top part breaking off doing so! Absolutely want to prevent that! What say the experts? Andrew

Seeburg RCSU3 stepper not playng any number "1" selections.

Hi, I installed a rebuilt RCSU3 stepper in my 222 Seeburg. (It replaces the TJU2 Tormat Junction Unit). My Tormat Selector is Type TSU1...Code A) Once installed the jukebox will not play any selections ending with the number "1" (A1, B1.....etc.) made from the wallbox nor from the jukebox selection buttons. All other selections work fine. When I put the Tormat Junction Unit back in place of the stepper, all selections including those with number "1" work fine. Stepper units are foreign to me and I can not find much info online. My Seeburg manual has a couple of pages on adjustments but nothing on trouble shooting. I'm thinking that something is not resetting completely or there are dirty relay contacts somewhere. I'm not certain if it matters but the 3-pin plug on the TJU2 has 3 contacts and the plug on the RCSU3 only has 2 contacts. Can someone point me in the correct direction to start looking? Thanks in advance, Bruce

I've got a customer with an R-90 that had a dead battery. I replaced it and set it on free play. Now it wants to play every record in sequence. I tried memorec clear 699 and checked that Autoplay is off. -- Paul Howlett Pinball Paul's 703-361-0420
