Hi El Donkey
I have one of these amplifiers (Beard AS P50 Power amplifier), and both meter lights are out and would like to replace meter bulbs. Have scanned unit but access to replace bulbs perplexes me and really don't want to disturb things unnecessarily to access. Did you ever manage to replace the meter bulbs yourself ... and if so how? I was hoping the amp designer would see this as a servicable part and allow relatively easy access?
PS my P50 amplifer also hums a little (not intrucively and only slightly noticeable when no music playing)) but I (no expert) just accepted this as transformer generated noise which was part and parcel of a vintage valve amplifier? The sound it produces in my humble opinion greatly outweighs the faint hum. Had amplifier for about 30 years but not from new so no idea if there was no hum when new.
Any tips on meter bulb replacement for this amplifier greatly appreciated.
