Penta amplifier beoparts kit

3 replies

As i sort through this kit, im finding some capacitor values are different from what is on the board.

In particular C22 has a 220uf 50volt in there where the kit shows a replacement value 470mf 25volt.

Is this correct   ?

It doesnt appear that anyone has been in there before me !

In case someone else was wondering about this, Martin responded with a confirmation about the C22 value of 470uf 25Volt.

Im trying to set the trim pots as instructed with no source and no speaker load. The amp will only power on for 3-4 seconds and only in the "link" position. Both amps act this way and its not enough time to set either pot. Because they both do this, i suspect its normal.

How do i get the amps to power up and stay on ?
