:) Glad you like it! Was a little sorry to see it go but I couldn't justify keeping it with the Savage reigning supreme in my music room. Hope you get as much pleasure out of it as I did...
Indy (& anyone else wondering): The Single/Dual/Triple Rectifier naming actually refers to different things on each model - the Dual rectifier has a choice between silicone rectifiers & a pair of 5U4 rectifier valves, the Triple rectifier has the same but being a 150 watt head needs 3 5U4s. The single rectifier doesn't have a switchable rectifier option & is 50 watts.
The model Joe has is one of the very early 50 watt Single Rectos - 2 channel, 50 watt 6L6GC power valves. Later Single Rectos have switchable bias for 6L6/EL34s. The later Dual & Triple rectos have 3 channels rather than 2. There are 100s other differences, but that's the bare bones of it. Here endeth the history lesson... :)
