Matching output tubes for push-pull service at a single operating point is of no value. The only way to get things correct is to use a curve tracer. http://aeaaudio.com/matching-tubes-with-a-curve-tracer/ https://vacuumtubearchive.com/volume-13-number-6/ Maynard

You should consider hiring a professional theater audio technician to do an analysis of your needs. In my opinion, for a venue of that size, you would need a pair of Klipschorns or Jubilees! And, even with those, you will need far more power than a little SET can provide. Maynard

Room size, distance from speakers when listening, distance between the speakers, type of music you listen to, and listening level will determine how much power you need. As with other speakers, the impedance of the Heresy varies with frequency and is not much of an issues for a SET. Maynard

Not from me! At present, I’m retired from doing any amp design work. There are custom amp builders around who can design and build anything you want. You may want to try posting on DIY Audio. Maynard

Three of the most powerful gospel soloists I have heard! Pastor Jeff Steele with his family, Pastor Charles Billingsley with Thomas Road Baptist Church choir, and Gerald Wolfe with the Cathedrals. Maynard

Beautiful rendition by Stonebriar choir. Maynard

Amy Manford with MTC. Gorgeous! Maynard

Henry is quite well! At present he is pursuing other interests . Maynard

Here’s the original thread. The schematic is a pdf between the pictures in the first post. https://community.klipsch.com/index.php?/topic/159805-the-long-awaited-little-sweetie-mono-sets/ Maynard

If I recall correctly this was a decent unit which could provide around 12 watts output per channel. Certainly enough power for most Klipsch speakers in my opinion. It would need to be thoroughly checked by a good technician and will need to be restored. Maynard

I speak with Henry almost daily and he is quite well but is pursuing other interests at the moment . Maynard

Another great performance by First Baptist Dallas! Maynard

Very powerful voice of Todd Strange with Hour of Power choir! Maynard

In my mind the question is what can we do to make poorly mastered recordings sound pleasing? It reminds me of those with the dreaded 10 db boost at 10 kHz. Tone controls do allow such recordings to be more listenable. Years back, if I recall correctly, there was a guy on the forum who remastered his music library to make the recordings sound as he wanted them to. Is that any different? Maynard

I don’t consider shaping of frequency response to be a non-audiophile endeavor. There is a reason why the high quality, now vintage, amps and preamps had tone controls. For years I have included an “ear bleed filter” in all my designs to allow the high frequency response to be altered to suit individual taste. Besides, many consider all tube amps to be nothing more than tone controls with gain. Maynard

The less “stuff” in the signal path the better, especially if the device is powered. As long as you can drive the amps to the levels you desire all is well. If a source has variable output, direct connection to the amps would be ideal. Maynard

Indeed!!! As many are aware, I have always been an advocate of using flea power amps with Klipsch speakers. Push pull triodes are considered the ultimate way to go among many audio folks. My personal preference has been to parallel tubes (whether SET or SEP). It is possible to achieve very low distortion levels in single ended operation by proper choice of operating point and circuit design. Maynard
