Hey!

   Great work on the amp there! Nice and clean layout. And yes caps take sometime to burn in.

   By the way, I love NOS DAC. I have a simple NOS DAC based on TDA1543 chip. I wish I have money to try Audio Note or Audio Note Kits DAC.

  Again, nice job on the amp.

Yes a credenza. I am pretty gobsmacked by how it sounds out the gate.the caps def need some burn-in but vintage transformers?

Those vintage transformers probably haven't been used in a long, long time, yes? If so, I believe they need to burn in as well.

About the credenza: My parents bought a teak credenza in 1978 and kept it until my mother passed recently. It is now in my home office. It wasn't until about three years ago that I learned its proper name is 'credenza'. From 1978 till three years ago, my whole family called it a 'buffet'. I have no idea why.  :lol:

Thanks SET Man!
I think you are spot on w the transformers. Put records in it like I do, call it a credenza. Put dishware in it, and we can call it a buffet all day. We definitely like it. Holds and hides plenty records and those pesky untidy cables   :D

^ yes. But my ear needs to be basically on the driver and it’s very minimal. About the same as my decware zen. The amp does have a hum rheostat located on back. If I tweek it full left / right the hum increases. I have it set dead middle and at a hands length away you are hard pressed to hear anything. Considering the speakers efficiency it’s acceptable.

No is not acceptable.......We just accept thinking: well is a SET
I don't see a reason why the builders these days don't go DC heated?
You will love the black background with way more details at lower volume.

I have a linear tube audio. I’ve never heard a quieter amp tube or solid state, period. The dht 45 sound very good at low volumes and is different enough from the LTA, and that was the goal. Achieved.

I’ve had the amp playing for the better part of a week. Yes, I have nothing but time :duh:
The highs sounded a bit rolled off and some passages sounded a bit grainy at times. This seems to be improving with time. The Alan Eaton is amp is wonderfully musical. Tons of prat! It throws a large soundstage, layered (improving) and is scorching fast. A lot more powerful sounding than the 1.5 watts would lead you to believe. It reminds me of my old decware zen. From memory they share more in common than not, but the 45 set has a bit more presence overall. Slightly meatier midrange, deeper bass, and dare I say just a touch quicker sounding. The Zen may be a bit more resolving, again all this from memory. Both amps can put the goosebumps on you and do! It really likes being driven by my Herron vtph-2a and audio mirror dac directly, sans preamp. May need to try a passive so I am not swapping rcas? The smooth dual gain controls begin at noon and gets loud by 3. A bit quirky and I do wish it had a larger range. Most of my listening is done at 2. The L/R gain controls do allow for fine adjustment, which is growing on me quick. I can hear a little power transformer buzz with my ear on top of the transformer. It’s worth mentioning, but not a distraction. Alan calls them lemons inside and assures me it’s fine. It self biasing but has a military grade rheostat on the back. The rheostat works in place of a resistor that way you can fine-tune and compensate the balance on the output tubes. The amp was shipped with tubes of different manufactures but they work. I swapped in some NOS hitachi 6sn7 yesterday and it responded well. Waiting on some tung-sol 45’s from vintage tube services. It’s definitely a quality tube amp with some nice vintage parts and solid looks. I do believe those old Japanese Tamura transformers Alan swears by, bring something special to the sound, along with the famous 45 toob! It has excellent synergy with my 3xrs ho speakers. I reckon with all omega speakers. I like being able to swap between it and my little LTA integrated for a change of pace, although I haven’t felt the need to swap.

How is the Alan Eaton 45 settling in?  I’ve been I touch with him to get one as well and I’d love to hear how it has been living with it.

I suppose I haven't updated in a while - sorry. I have had too much fun listening. The amp has improved nicely (smoothed out, larger soundstage and more layered) in the last 6 weeks. As mentioned, it has wonderful synergy with Omega, Audio Mirror Tubadour III DAC and Herron VTPH-2A. The music coming out of these speakers is just so coherent and real sounding - it just flows. I suppose it has an old-school flavor but lightning fast, very powerful, with tight tuneful bass. Rarely does a recording ever sound forced. While I have listened to amps/speakers with better resolution, I am hearing things in recordings I have never noticed before. And again, it just sounds real!
When I first chatted with Alan about building the amp, I emphasized music as being the most important consideration. And I can confidently say he delivered a very engaging musical amp  :D
