non-reverb WonderDawg LunchBox

I recently had a request by someone for a single channel, non-reverb amp that used the blackface AB763 circuit as the platform, and it needed to be a small head with 25 watts of output. After some discussion we settled on the WonderDawg for the platform to begin with, and after removing the reverb portion of the circuit I was able to fit the circuit into a 12×8 enclosure which was exactly what the customer was hoping for. One of the added benefits of this amp was that with the transformer set used it’s also possible to re-bias for use with 6V6GT, 5881, or 6L6GC power tubes. The amp does have external taps & adjustment pot for biasing without the need to remove the cage or bottom, or the need for an amp tech as I sent along detailed instructions of the process as well as pics of it being done on the amp to the customer.
