I do like a challenge. This VOX AC30 BASS is dated 1991 and I fully refurnished the amplifier after much time spent sourcing spares of the correct type, size and specification. Luckily I had most items in stock.
It has now a new power supply 5AR4 valve, a quad balanced set of EL84s from Svetlana and a lot of care and attention. New Volume control and panel lamp. Sounds wonderful again.
