Thanks Gary. Funny that I don't remember the tube amp. Glad you like the horns.

The Hammond 126C is really good for it's price point - bifilar wound. So I'm not unhappy, but I'm sure it can be improved. The O-netics OPTs are good. They're the small "commercial" model that Bud makes, and he's been quite rightly suggesting I upgrade to one of his better models. I could do with a little more bass - maybe a larger OPT. But the bass that's there is tight and detailed so I'm not unhappy, and in any case the lack of extension is the speaker's problem - Alpair 10s in infinite baffles. I should port them to get the extension, but I just like the sound of closed boxes.

Do you have any suggestions for a 3K SE OPT, or somewhere from 2.5K to 3.5K? I haven't tried James either, and they are a contender.

My everyday amp used in my home-office....

Built mid-1990's and based on the Maplin Millennium design but with mains transformer from the 1960's, 2 x GZ34 rectification (one for each channel). Replaced PSU caps, a few resistors and EL34s last year (after these photos were taken). Still giving very good service.

Your memory seems to be better than mine... After some thinking I remembered that the crossover between the Beta-8 and the HiVi RT8 was passive. The system went to full 3 way active after you left P town.

I do like the horns. They are a neat mixture of more detail and better tone and texture.

Ukrainian monoblocks (6B4G in PSE, no feedback, 2C51 and E288CC driver) I bought broken and had to rebuilt:

Now it sounds like dream and I can't stop listening to.
I'm listening to it several hours a day and often all night long sleeping with music.

Preamp is handmade by me, as well as tube output DAC (picture taken in DIY room at "Audio Show", an exhibition of audio stuff in Poland):

These days my "everyday amps" have become my Altec 1570B twins. I have recapped them and replaced all tubes and they sound heavenly! I also did a few things with the cosmetics because these amps are truly ugly as-is! I blacked out the whole thing except for the large cans in the front and the tubes. I then put an edge lit engraved plexi front on them.

My every day amp is SS but my mixer is valve.
I use an ecc82 valve. I have 2 stereo inputs, a guitar input and a mic input.
The stereo channels only have 1 stage of gain where as the guitar and mic have 2.
All the channels are mixed into one output channel.
