OK Guys and Gals,
Here are my three new Mark III clones with Poseidon drivers:

There are three pictures. If you click on the "album" link just below the picture you can go back a page to the other two pictures plus others if you like. Or, you can click the "previous" photo at the upper right.
I just finished them this evening. I was waiting for the plate load resistors for the phase inverters. I didn't have the new 68K ohm value in the junk box. Soldered them in this evening when I got home and fired two of the amps up. I had previously fired up the one on the left. Yes, those are geeky blue LED's in the octal socket centers. Only the right two amps are on in these pictures driving those kinda grunchy speakers in the background.
Well, they are brand new and have not even stabilized yet but they sound great even without the best speakers I have and without my best CD player. So, I am estatic! These will replace my eiclones as L-C-R amps for my tube-based home theater. The eiclones will be moved to drive the rear speakers now after I make Shannon's previously posted mods to them. I'll send a picture of the whole thing when I get it all modified.
What fun! I don't know yet but these sound as good as my ST-70 when it was driving those speakers. I'll hook them up to my A-25's after they settle down a little. But they have lots of punch and what sounds like a great top end. The speakers in the picture are very "bright". The tweeter output is overpowering the woofers. I'll someday have to adjust the crossovers. I built those a while back from a bunch of sale parts from Parts Express. Even so, they don't sound too bad.
Anyway, another fantastic set of amps. Thanks Shannon for the driver boards and the inspiration! Now I have a set of Eric's HF-89 clone transformers to do something with. Those should be really impressive sounding. (I mentioned before that I'm addicted and I really am.)
Regards,
