Hi,

Sorry, no idea of the faults.

That is some piece of kit you have there. Dual tda1541a s1's possibly in differential mode.

If i earned more I would buy this ebay one. Shame!

Kind regards,

Ashley.

I think there is a problem with a part that gets hot. Probably a bad soldering somewhere. Check the soldering of all parts, start with the one's that get hot (powersupply stuff). happens a lot.

I have one also. It does not like 48hz, will buzz and lock up. With a 12v 12ah battery it will last about an hour. With direct current from adapter and a 44.1hz feed, no problems. It has a 3 amp fuse, shouldn't it last longer?

Does anybody have more information about this beast ? Schematics or service manual ?

I have found one off eBay and it seems well built but for the moment, lacking sufficient technical info, I am reluctant to dismantle or mod it.

The only schematic I found is partial and contains only a drawing for the output stage.
