Is there anyway to prevent r31 and c71 vulnerability from feedback? would a diode help to shunt the feedback voltage?

Sorry?, I'm completely baffled as to what you asking?.
R31 is the feedback resistor for the power amp and C71 (along with R53) is a Zobel network.
I know I'm late to this, but it's interesting that the values for C71 and R53 aren't the manufacturer recommended values for a TDA2050.
Need AVT-20 schematic-Marshall Valvestate 2000-----Also Guild Thunderbass head-joetee9@optimum.net Thanks
Did you not read the thread?
Right from page one, several people offered to send out schematic if they were sent an email for it, and I even posted the schematic right here, seven posts above yours.

Thanks very much - just rebuilt an old Fender Vibro-Champ, now time to get my hands dirty modifying a transistor amp... oddly enough, the first target is to REDUCE the gain in OD mode to get rid of some of the white noise...

alot of people are having a problem with avt20's
with r53 burning out and excess noise, and this is not the only forum
audio-talk :: View topic - Flamin' Marshall AVT 20!
has other information on this problem that may be usefull,
or if any one can help me on this
i replaced:
the ic chip - lm1875t
c71 - .22uF 63 volt cap
R53 - 10R (1/2 watt) resistor
and fixed all dry solder
the problems i still have are:
R53 just burn's out when turned on, however it doesn't burn out when the amp is running an external speaker cab?
and there is high frequency whistling and noise whether the amp is running its own speaker or a cab..... also there is excess noise but not the same whistling when the amp is amplifying the c.d. input.
