Hello,
I also picked up a Seeburg DS160 with that Wurlitzer 2810 that I'm trying to get started first but on the seeburg ds160 when i opened it up i found i need a amp which i think is the 545 amp and a tormat unit. i searched around the internet i have not found anything on either. if someone knows where i can find one and a price i should would appreciate it. Or if i should just forget about it and scrap it. everything else seems to be fine on it, it even came with the two side optional speakers on it. Thanks!

Sorry everyone,
I got the amp number wrong on the Seeburg ds160 i was looking for that was the amp for the Wurlitzer. But I need the seeburg ds160 amp and tormat unit.

Check the announcements section above--where to find----I am sure all those parts are available--

On the Tormat, you should be able to use one from any of the early 160 models: 161-222-Q160-AY160 and of course DS160. Do ask if the Cinch-Jones plug is in good condition and that there are no broken pins.

The amp for that machine is an SHFA-5. This was Seeburg's last gasp tube amp. The amp itself has a more pure sound and fast (transient) than the earlier versions due to simpler signal path and no huge feedback loops in the tone circuit that produced big peaks and dips in the response. But as a result of that and the too-simple preamp they do sound a bit thin as compared to what tube machines normally sounded like.

In the two machines I worked-on w/these amps I bypassed the existing preamp and used an external which I slightly modded (not really necessary) the end result was better, more typical sound along with the benefit of the simpler circuits.

Minor problem areas:

The AGC diodes will have to be replaced for the channels to balance properly.
Looking at the schematic: http://www.verntisdale.com/schem/shfa5.jpg

CR102 Can be replaced with one silicon diode each

But for CR 103 and 104 you'll need to string 2 or three in series for each being replaced. this is due to the lower internal impedance of modern silicon diodes. I generally use 1N4001 or 1N4002 for all.

Decent 7199 tubes can be a problem and the volume control on those amps is high impedance and they can change in value to the point where there is a different curve on each channel.
