I got this amp off a friend of mine and it appears someone tryed repairing it themselfs..

Im going to rebuild the output driverboard since it looks like a bad reapir

There is a diode missing its marked B2F any ideas on what part number that may be??

I already call DD and they have nothing on the driverboard

The diode goes between the SD pin (pin3) and the COM pin (pin4)

Any ideas on what this may be?

What doesn't the amp do that warrants a driver board rebuild?

S Merlington 16th August 2012 01:21 PM

Amp doesnt power up and i can take some pics of the driverboard and you will see why it needs rebuilding..

Both boards have been messed with and well i can let the pics talk for themselfs if u wanna see

The SG3525 in this amp has 0 volts on all pins..

What pin or pins should i see 12 volts on ??

Just wondering so i can start tracing the circuit back

15 and probably 13.

I will check the part number of B2F in my Z1 and will let you know.

Could you, by any chance, figure out the zener-voltage or partnumber of diode D4 on the small PSC-029 (power supply) controller-board in the Z1?
Thanks in advance.

Enclosed a pic of the PSG-029 controller-board in my Z1 with the missing Diode D4. Please let me know type number or zener-voltage.

Sorry, previous picture was wrong one.
Enclosed the pic with missing D4.
