Re: Tube/valve amp kit question

Look through the various old DIY audio books and see if anything
strikes your fancy. Scratchbuilding will be far more educational of
course. Modern books worth reading include but are not limited to
Morgan Jones' Valve Amplifiers and Building Valve Amplifiers, Bruce
Rozenblit's Beginners Guide et al, and-not intended for DIYers but
useful- the VTL Book.

http://www.audioxpress.com is one US based source.


In the UK you might contact Sowter Transformers who wind classic
GEC/Mullard , Leak, and Radford OPTs, and the kind of amps you can
build ultimately comes down to what transformers you can get.

You could of course build the old Williamson design, which with a pair
of about any beam power tubes strapped triode, gives roughly fifteen
watts, or twenty if used with an Ultra-Linear connection.

I would avoid anything using EL84s, and unless you are very wealthy,
true triodes. Single ended is a deluded crock and you would be advised
not to waste your time IMO.
