Default Re: Grundig TK27 - Low audio output

I am somewhat surprised that HT voltage is not higher than 265V with the EL95 output pentode removed, this is the main load. So at this stage I personally would not strongly suspect it.

Have you scope measured the HT ripple in case it is excessive, should not be with the new filter capacitors.

Later when I get back home I will do comparison readings on my TK 27.
