I built this about 5 years ago, and spared no expense. It's upgraded with Goldpoint dual mono attenuators and a Goldppoint selector switch, Goldpoint knobs, upgraded RCA jacks, silver wire with teflon sleeves and Superior Zcap capacitors, which were the recommended caps in Troels Gravesen's workup of the GG preamp (see link). It also has a custom made faceplate from Front Panel Express, and a really nice blue LED pushbutton power switch. The preamp works perfectly and sounds terrific. It's currently set up for 12dB gain, but this is easily changed to 18 or 24dB with the swap of 4 resistors.. I have paired this with Quciksilver Horn Mono amps (very nice pairing), Welborne Star Chief 45 monoblocks, Alan Eaton 45 monoblocks, a First Watt J2, Odyssey Khartago SS amps and I'm sure a couple other amps I can't recall. It pairs easily with a wide variety of power amps. It is in great shape, functions perfectly and sounds terrific. The only cosmetic defect is one corner of the case, but it is totally behind the faceplate and not at all visible. And it obviously doesn’t affect the performance in any way (and it looks a lot worse in the photo than in real life). I will include any spare 12au7 tubes I have in my stash, as I don’t have any other equipment that uses that tube. It will, of course, ship with a full complement of tubes, and a generic power cord. Asking $700 shipped.  Or, I would entertain a trade or partial trade for a quality CDP or transport, or a standalone R2R ladder DAC that would be an appreciable improvement over the DAC in my Cambridge CXN v2 streamer. I’ll cover shipping in the CONUS. Contact me with any questions.

Thank you very much for your kindness! The tips on soldering are nice, we learnt it at school but long time ago, so first, training on dead / needing repair electronics will be the way. We'll avoid the fine connection wires as well, but I saw many people were rejunevating their speakers by using new diaphragms so I am quite curious about it as well.   Yes and your Khorns wood seems to be a great quality. One of the Heresy speaker is almost fine but another have several mm of space between side pannel and front pannel. Turned out that's why those speakers had internal seals. I have no idea why they didn't reseal them properly at the time but that's what I intend to do this time. 

Never owned a SET amp but, the PP tube amps that I have owned all had excellent bass.  They all could put out over 25 watts at a minimum and ovcr 50 watts per ch. without  a problem.

Five hours with the leaves? Dang. I'll spend an hour getting my ride cleaned up some before I head to the grocer and the gas station. Got to remember to get more tire-air also it's been close to cold in the mornings here. Took my bank up on their early payday thing for the first time today. So making myself wait until after I have coffee, sausage & eggs in the am before I do that run.    

@KROCK Yea, that's her.  She hung around for a while.  Had her jeans on hidin those bruises from the stripper pole.   😂😂😂

I would not remove them as they are part of the phase-plug assembly I'd be curious to see where you read that info and who wrote it

5 hours w/the cub cadet pullin that lawn broom.  75 today and a  bit windy so wasn't too bad.  Thing is.  It hasn't even started yet!  Crzay!  lol

It's not quite like that here Dave, but that's funny! Going to fire up that leaf blower tomorrow, I did last Friday... You can't even tell because the leaves are pretty deep even on the driveway. Things are different up here!

Dr Morbius -- the website isn't letting me upload photos, its giving me an internal error... As the post states, you can always reach out if you have interest and im glad to provide them.

Question. Seems as if I was reading that when replacing the diaphragms on the KLF 10 horns that there was mention of modifying the wave guide by removing the plastic cross section at the throat of the horn. Are we doing that when replacing the diaphragms or am I just not recalling correctly. Thanks.
