Ok im guessing theese resistors are all 10 ohm resistors..

R203 goes to pin 4 of the TL074C
R204 goes to Pin 11 of the TLO74C

R118 goes to Pin 4 of another TL074C
R117 goes to Pin 11 of the TL074C

Wow i over looked alot of stuff..

If theese are 10 ohm resistors every one of them is defective going to every op-amp on the preamp board

Board number MVP183?

R203 appears to be a 0 ohm jumper. R204 is a 10 ohm resistor.

The Preamp board Number is MVP184-B

On this board R203 appears to be a 10ohm

So far i found the following resistors bad

R203,R204,R111,R112,R117,R118,

Which appear to all be 10 ohm resistors..

Ill have to put this amp aside til tuesday until i can get to the stire and get some 10 ohm resistors..'

Do you think any of the op-amps may be defective??

Wondering if i should pick some op-amps up as well ??

This is the same board as the 7801. I was looking at the 4501 board.

R203 is 10 ohms.

The op-amps do sometimes fail. It's just like the op-amps on the main board. The series resistors sometimes protect the op-amps but not always.

Back to this amp..

I replaced all 10 ohm resistors on the preamp board..

When i power it up the amp will draw 10 amps of current and no lights on the preamp board light up..

After i remove power from the amp the lights on the preamp board light up for a sec..

I noticed R122,R112 R121,R203 burnt up within 2 secs..

Does this mean the op-amps could be defective or what do i need to check next?

If those resistors are in series with the +/-15 and the op-amps you need to replace them.I usually always have to replace all the op-amps on these MTX amps when the voltage regulators short.
