Currently I use a 6SL7 based voltage amp/driver with it's own power supply/chassis to an EL34 current amp with it's own power supply/chassis. The EL34 amp has some negative voltage gain due to the OPTs but the 6SL7 driver has plenty of gain. EL34 amp has a low-esr film cap power supply w/5AR4 rectifier.

Speakers are my own wide-range LeCleach horn with 15" woofer and super tweeter.

Any photos of your speakers, Dave? Can you tell us about choice of drivers and crossover.

No, it looks worse than the prototype AF0 right now! I need to get the final prototypes built. :)

Drivers are my own, but most credit has to be given to Louis of Omega speakers. He's a very talented driver designer who helped with getting the FR right for the horn it's going in. It covers 400-15,000 Hz. It has no real xo, but uses a single cap to cut bass.

Tweeter is Fostex T500A MkII also with a single cap for xo.

Woofer is Acoustic Elegance TD15H+, which is basically an 18H+ with a 15" cone, the cone is stiffer and the motor is larger vs the regular 15H. It's run active w/ 24 dB xo.

A Line Magnetic Lm508ia (with either a Microzotl preamp or Shindo pre) into Pureaudioproject Pap horns or Harbeth 40.2s but not Magnepan 20.7s, well not yet at any rate... indecision is clearly a strong point here. I may yet modify the Pap horns, I would love to maybe modify the 20.7s with neodymium magnets, I wouldn’t change a thing on the Harbeth 40.2s...

I have ancient Cary 2A3 Signature Monoblocks (3.5w/ch with Psvane Treasure tubes) driving equally ancient Avantgarde Duos, both from the most recent fin de siecle.

I'm running a pair of Lampizator 211 True Balanced Monoblock amps. The amp only accepts a balanced input and there is no phase splitter. Essentially, each monoblock amp has two separate single ended amps. Each phase of the input feeds a separate 300B driving one 211 output tube. The outputs of the 211 tubes are combined in a single output transformer. No local or global feedback is used.

I'm biamping VSA VR100XS speakers with the 211 amps running the mids & tweeters. A pair of Spectron monoblocks drive the woofers and feed the XS subwoofers at the rear of the room. The 211 amps are spectacular on the M/T with no global or local feedback. The Spectrons have a very high damping factor that provides vice-like control of the woofers.

Best,
Kernelbob

Line Magnetic 503pa mono block set amplifier. Coupling caps upgraded to top Duelund and signal resistors upgraded to Audio Note tantalum. Tubes are Takatsuki 274b rectifier, Psvane replica we300b plus, psvane replica we310a with psvane acme 845 on the way.

My set amps drive 4 channels of horns playing from 120hz and over (120hz-500hz / 500hz-5000hz / 5000hz-12000hz / 12000hz-20000hz). Lower channels (4xTad 1601b woofers for 40hz-120hz and a full size tapped horn for 20hz-40hz) are driven by 3 ss amps.
