My McAlister Audio tube amp finally arrived this week. It is a 75 WPC push pull amp based on the Williamson design. The power supply is massive and seperate of the amp. Tube compliment is four 6EA7's for the input/drive section, four 40KG6 horizontal output tubes and one 6AX4 thermal delay tube. The 6AX4 delays high voltage for a minute to prevent cathode stripping.
A friend of Norm's (Normanality) put us on to this amp. This guy is a radio personality down in SC. He has quite an impressive list of previously owned gear and parted with it for this amp along with one of McAlister's tube pre amps. Norm is still waiting for his amp, which is a darn shame cause he ordered his a week before I did. :D We are also are having tube pre amps with phono sections built.
McAlsiter is a one man band up there in Canada. He winds his own transformers and does all the assembly by himself. His knowledge of tubes and circuits amazes me. He does custom work as long as it does not compromise his design. It's kind of plain looking and I've seen prettier stuff, but I lack the audio terminology to describe all the wonderful things I am hearing with this amp. It is one incredible value for the price paid.
Hopefully Norm can get over this weekend and help me give it a serious listen. If there are no guests to entertain, I'll get assigned chores to do.
