im pretty much rebuilding the amp from the bottom up amp has been robbed of almost all parts just having trouble identifying a few parts the outputs are missing wondering if anyone knows what outputs to use and there are 2 parts missing off board they are marked vr101 and vr2 for the board locations if anyone knows what belongs there it would help wonders thanks for the help

post a picture of the board and whats missing, someone here will probably be able to help you then. I would asume that board designation for VR is "variable resistor", am just guessing.

In case no one can help with a gen8, I have a gen7. The parts may be the same.

Outputs are TIP35C/36C

The pots are 2.2k

thanks perry i will post a pic of the amp as soon as i can not sure now that i look at the amp on what fets i need the fets that are still on te board are the irfz44's sgsd200's and 100's and the tip 36c's and 35c's and e15029's and 28's then the others are missing board locations q106 through q115 not sure what fets go there any help would be greatly appericated

Are the 200 series parts (206-215) still in the board?

If so, they should be the same.

I'll check the amp when I get back to the shop.


Of that group of parts, Only the Z44s are FETs. The rest are bipolar transistors (BJTs).

thnks perry for the info wondering if u might have part numbers from digikey or mouser for the pots and there is an ic chip missing in the amp on main board looks like maybe an opamp might go there wondering if u might know which one i need it sits behing the rcas

[Perry Babin]

This is the closest that Mouser stocks. The pots in this amp are marked 2k2 (2.2k ohms) but read 2k on the meter. This is a 2k ohm pot:

531-PT6KV-2K


Do you still need the transistor part numbers or were you able to get them from the 200 series parts?


On this amp, there is a TL072 under the RCA jacks.

im gonna order some parts for this amp later theres 2 spots on the board marked 2k8 5 watt im rhinking theese are sandstone resistors wondering what ones do i need to pit there and where can o get the 2sc2061's at

In the series 7, there are two 1,8k 5w ceramic resistors. The value may have been changed to 2.8k (1.8k, 2.7k?). Virtually any 5w resistor of the correct value would work but I'd suggest that you use ceramic resistors if that's what was there.

the amp is a zeusviii series 1 i think and wondering the is 3 locations for variable resistors do i ned 3 of them?
