was right, there's a pair of 30K and 2K7 10 Watters next to each other.

I would do a thorough check on the amp: the two resistors are B+ droppers
for the preamp/phase splitter and shouldn't dissipate more than 3 or 4
watts. If a 10-watt R has burned, something must be very wrong somewhere
else.






Found the problem - the reverb tray input coil (8 ohm) was shorted. The 2K7
resistor supplies the reverb transformer primary via the 12AT7 driver, which
I have now replaced. Now just waiting for another tray. Incidentally I
have never been able to find these values in 10 Watts here in the UK, I used
to have to get them from Fender. The 2k7 is now a 22K and 3k3 in parallel.


Thanks to all,


Gareth.
