ONE SINGLE VALVE
NOTE – we recommend that only a skilled / trained technician replaces valves. There’s a lot of very high voltages inside your amp and a very real danger of getting a shock.
Also these are very fragile and should be handled with the utmost of care.
Note your amp may require a bias adjust.
You may damage your amp by replacing valves without correct adjustment.
