    Hi Guys

    Upon switching on my LA Audio A30 valve amplifier this morning one of the valves from the right channel was not lighting up so i swapped it for another EL 84 and still the same problem still no light beginning to think its the amp that has the fault swapped for the other good valves to still no joy? We bit down in the dumps about this - any thoughts on repair?

    I had the same on the pre-amp side of on of my valve amps and it turned out to be a failed capacitor on the heater circuit, luckily no damage to anything else. I was advised that it is not always a good idea to power them up with a failed valve or circuit in case it overloads elsewhere, but you should be OK. The repair hopefully will be relatively cheap on parts.
