[Amps] Tl- 922

[twobusyracing]

Kenwood tl-922, the amp burnt up the R7 resistor and pecked the ip amp gauge, i've replaced the R7 resistor, and had the ip amp gauge repaired, but the issue is still there!! I've since fitted the don Kessler tl-922 kit, for several improvement reasons, thinking the zener diode was the cause,but no the issue is still there. I have checked transformer taps, chocks, caps, as well as ohms tested the tubes, allthough after a little research ohm testing 3-500z tubes is pointless apparently. I have exhausted my limited knowledge on electronics, any advice in the right direction would be of great assistance. Much appreciated walter     Sent from my Samsung Galaxy Tab S2 on the Telstra Mobile Network
