Then they must be good. Still have around an LA Audio tube power amp that sounds decent considering that it is 20 years old. I always come back to it for reality check.

Will MJE 15032/33 be ok as the powertransistors in the Paradise?

Would be nice, since i have a good handfull of those in stock.

When the footprint is the same they will work.

pdul · 9th September 2012, 06:49 PM

Ok

Thats a very low demand.

pdul · 9th September 2012, 06:50 PM

Thanks

Base, Emitter and Collector should come out of the correct pin. I know, this is pathetic but Japanese transistors often have another Pin Out. On Semi uses the European system i think.

They are On Semi, and they are BCE like tip31, so the pinout is ok. It was more the other specs i was unshure of

I have another question. What if the chokes are connected on the primary of the transformers instead of the secondarys. Wont it have the same efect on RF filtering?

I have shown a circuit how to connect the Telamas correctly.
As ripple filters after the bridges they are more or less useless.

You can find the circuit in post 7192. They belong behind the transformer and before the bridges.
