This 20W combon has a Parallel Class A Single Ended output stage - the harder you drive it, the better it sounds.
It is powered by 3 x ECC83 preamp valves, and 4 x EL84 output valves. These were were fully replaced with a Harma upgrade kit from Watford Valves 3 years ago. It has a spring reverb, clean channel, gain channel, high/low inputs, fx loop, bass/mid/treble controls, and a separate high end tone control (at the end of the circuit) which acts as a really nice top end cut or boost. It's an early UK handmade version (serial 0044) before production was moved to China.
The amp is heavy - about 16kg - but has never let me down. Gigs are getting smaller and quieter, so this amp is a bit beyond what I need these days. It's sounds great - I have a video clip of me playing it I can send as I can't work out how to load it here.
It has been my main gigging amp for the past 4 years, so has been in and out of cars and vans, indoor and outdoor gigs, and in and out of rehearsal spaces. As such there are few blemishes as you'd expect and can be seen in the photos. There is a slight discoloration to the front grill which was there when I acquired it.
It comes with footswitch included, allowing you to easily flip between clean and gain channels, and remotely switching the reverb on and off.
Due to the weight, collection is preferred. I'm also happy to meet half way within reason.
