"Tube amplifiers, built in the last, four years ."
Wow, they look great; an impressive body of work!
It took me 7 years to build just one...the upside of that long time line was that I re-designed it several times, as I absorbed inspiration and knowledge about tube design from you-all! Thanks!

Was wanting to get back into tube amps, and decided to try out an EL84 based amp. Ended up with a Manley Stingray and even had it rebuilt to incorporate a few of the options that the Stingray II has. It just arrived back from Manley today, and I am enjoying the results. Really had no idea how much I had missed a good tube amp.

I can't believe that I didn't take better notice of your wiring here! This is exactly what I try to tell folks about making a 'decent connection' to begin with and not relying on the solder to do the job by itself. Making a good mechanical connection first is the best way to connect wires and leads. How many times have you seen a lead of a component laying across the intended connection and then a coat of solder applied to make it complete? Just not good. Winding a lead like what is shown here (although I don't wind several times, only 1 1/2 times) and then applying the solder is making the connection higher quality from the very start and not utilizing lead solder to pass a signal.
Couldn't pass up the opportunity to share this when it is so evident here. Good looking wiring paths to boot. Better than many manufacturers out there.
