Default Re: The BBC 1 Valver!

I've also got Davey's, "Fun with short wave radio" which also features a set based on a DF91 or DF92 and discusses mains one valvers, no doubt variations of the circuits used elsewhere. He does admit though that the one valve circuit is similar to the HAC one valver except that the latter uses a 2 volt valve.
