USC2 record reject and audio issue

[terryst]

I have a seeburg USC2. When I first purchased it the magnet had fallen off the trip switch. I glued it back on and everything worked great for a couple years. Then it stopped working again. What the issue is the record loads and the needle goes through the record and there is no sound. When the record gets done it will not reject. Also it will not reject using the  reject switch. I have checked the trip switch and it is working properly. So I found on the TSA10 Code B solid state amplifier that the main 1 Amp fuse is blown. I replace the fuse and as soon as you turn on the power it blows again. I have purchased all the documentation for this as far as the manuals are concerned. Service manual and all. So from what I can tell the amplifier may be what is causing the reject issue? I do have experience troubleshooting electrical components. I have disconnected the output of the transformer in the amplifier and the fuse does not blow. It is a center tap transformer and when I check the voltage I get 35 VAC on the 2 legs to the center leg as well as ground. I am not able to find anywhere if this voltage correct.
My question is would anyone be able to tell me if I am correct in my theory that the reject issue could be related to the amplifier issue?
And also is there somebody that could lead me to either a new or used amplifier or a repair person? 
Also is there some type of a current replacement amplifier that could take the place of the TSA10?
Your help would be greatly appreciated.

Thanks

Hi Terry,
Welcome !
Please read and comply with our posting "rules" as shown in the "user introductions" section here.
If you have a copy of either my Seeburg Mechanism Guide, or a copy of my Seeburg MicroLog Trouble shooting Guide, you can go to the "electrical operation" section of the Mech Guide, or the "amp notes" in the TBL shooting guide. Both tell the reader that the amp, (as you guessed) control the trip-off / reject function. ( contact me, should you wish to purchase @ [e-mail])
As for "Repair persons", please read our FAQ's section for "lists" of them.

Terry,

As Ron indicated, the reject switch not working is caused by a problem in the amp. I am by no means an expert, but have solved most of my amp and selection receiver problems by replacing the capacitors and in one case some transistors. A kit is available from the suppliers listed above and isn't too hard to install if you can do basic soldering. That same supplier will rebuild an amp if you ship it to them. Again, I am not an expert and don't understand the hows and whys of electrical components but changing them out isn't hard. Oh yeah, dont plug that thing in again before you find the problem or you may cause more damage, and use a dim bulb if you do.

Gentz,
Cap replacement is only about 50-60 % able to restore an amp. In this case, it's most likely NOT the caps causing this problem, unless the filter is shorted, which has been proven not to be the problem here. Also--if replacing caps on PCB's use a lower wattage (heat) iron !! Ron Rich
