I recently acquired one of these and had a question about the valve inside of it. Do you remember what type of valve this is (I would guess ECC83)? I haven’t opened the casing up, but is the valve hard-wired or in a socket? I’m just wondering in case I ever need to replace it.
That’s right, the original valve was ECC83, the only possible improvement would be if you can source a Telefunken E88CC. I have used those in the past and they produce even lower distortion and noise….. not that the ECC83 is too bad!
The valve is fitted into a ceramic valve base so it’s easy to replace.
