Any good idea to replace 20kohm volume pots on Altec 9440A

[Altec Best]

Any information how this amp sound ? Is it actualy worth spending time and money on it ?

I agree with OG.. These were excellent sounding amps.One amp in your system is enough and will sound great.They were typically rack mounted back in the day for live sound..Could you imagine 4 of these in a rack powering a stack of speakers.. Or some 210's ? Droolsville.... It is money well spent IMHO.
