I remember Hiwatt, their late founder was one of our customers for Red Lion (GEC) KT88s.

I should have thought of Rauch in connection with this thread seeing as I have one sitting on the studio floor at the moment. They did two ranges, the expensive DVT models and the cheaper Power Blocks which, from a quick trace through the circuit of mine, looked very close to the standard Hitachi MOSFet data book design.

Another two..
Nichols. Only ever seen the one. Glad I took some pictures before it went. Made by Ken Nicholls in Leyton, London.

Elgen. Tony Merrill owned Elgen amps in High Wycombe. I believe Peter Frampton used them for a while. Very nicely made gear.

Hi,

Crikey, not seen one of those Nicholls amplifiers in what’s got to be 40 years or more. I remember one of those coming into Roost for a service. Can’t remember who owned it, but seeing Leytonstone is only 30 miles from Southend it’s highly likely one could have been used by a group based in the Southend area.

When I first started work at Roost we used to service other manufactures amplifiers to help local musicians. Although not of British origin I remember a Ackuset PA system, once owned by the band Love Affair coming into to the workshop for a service – but this is heading off topic….

Going back to post #83 and the Rauch amplifier, from memory it was the Hitachi circuit but using an symmetrical emitter follower stage to drive the MOSFET's.
