Default Need schematic of Preamplifier AM 1065

Hi everyone !

I have just bought a pair of monoblock Pre-amplifier Type AM 1065. It had only the signal parts, so I want to DIY a Power supply for it.

Anyones have schematic of this one, please help me.

Thanks so much

I can't find the company listed, let alone a diagramme of the pre-amps. Work your way through it by using the valve types and pinouts to work out what voltage you need. The smoothing capacitor will give a good clue. Normally the voltage rating is 30% more than the HT presented to it. AC heaters of either 6.3 or 5v depending on the valve types.

The Filaments need to be 6.3 volts . I would use DC to them and the B+ should be around 225 to 250 DC , the filter caps are most likely rated 350 WVDC .Recap them so you don't do the transformers in .
To be better one must be different ,but to be different is not necessarily better .
