he circuit is the AB763 (non–master volume), which means it belongs to the very first Silverface series that essentially used Blackface-era circuits (Blackface circuit AB763). This makes it a particularly desirable Silverface, because in practice it is a Blackface Twin Reverb inside a Silverface cabinet.

The “drip edge” aluminum trim around the grill on Silverface models only appeared between 1967–1969.

At the moment, the amplifier is without its power tubes. The cost of the tubes amounts to 120 euros, which will be deducted, along with the technician’s labor/inspection fee. This in itself presupposes serious offers only, thank you.

I might also be interested in Strymon pedals, which could be taken into account towards the overall value.
