Default Morgan Jones' Bevois Valley amp...

Hi,

I was considering building this amp as my first PP project. Anything I should be aware of (gotchas?), and any recommendations for component suppliers in the UK/Europe would be appreciated. I know a few, e.g. Jan Wüsten & Sowter, but I'm a bit new to valves, and would appreciate any pointers...

Thanks

Nicko

Hi Nicko,

since you are from the UK, Sowter would be a very obvious and surely excellent choice for the OPTs.

Other makers of OPTs in Europe you can consider:

Lundahl (Sweden) - www.lundahl.se
Reinhöfer (Germany) - www.roehrentechnik.de
Automatic Electric Europe (Netherlands) - don´t remember
VVT Transformers (UK) - www.vvttramsformers.co.uk
Welter (Germany) - www.welter-electronic.de

And probably lots of others

Tom

Hi.

A little off topic but do you know why he called it the "Bevois Valley amp"? I'm from southampton and often stop for a beer in a bar in Bevois Valley.

In Jones’ book he says he bought a pair of mono tube amps from a junk store in Bevois Valley for 15 pounds. These became the basis for his new prototype amps (I assumed he reused the transformers and chassis or something similar). The resultant design subsequently became known as the Bevois Valley amp.

I did my EE degree at Southampton. ISTR Bevois (pronounced "beavers") Valley was a very cheap residential area popular with students. Rumour had it (though I wouldn't know!) that nominative determinism had played its part and that part of the "red light" area was there too...

I too went to the electronics junk shop, and bought an IBM keyboard amomgst other rubbish - I don't remember seeing any valves in there, but that was 25 years ago. Most of my valves etc. came from HL Smiths in Edgware Rd or Proops in TCR.

I live in W.Kensington and my valves came from Colomor (the original Polish guys) and the MO valve Co. in Brook Green. To think I used to walk up to the counter and get new KT66, Mullard EL34 and ECC83 etc. as many as you could want for peanuts, and within easy walking distance of my appartment...... If only we had time machines.

I built the prototype and have all the iron from Sowters (very nice).

Not put it all in a nice chassis yet - got a bit distracted (as is my wont) by building tube & solid-state tesla coils... get a lot of smoke from those...

Very nice, thank you. Clear and sweet. Very pleased.

Not nearly as bad as the effect on the neighbours' TV reception...
