Alan Eaton 45 Tube Amplifier

My Alan Eaton 45 Integrated Tube Amplifier

I’ve been building amplifiers for decades, and I discovered Alan Eaton’s 45 tube amp at the end of 2021. Finally I had just purchased the first superb speakers that allowed me to use a 2w/ch amplifier. This is not the first time I did that but the only time that I was pleased. So now it was time to purchase a good 2w/ch amplifier and I started with Alan Eaton’s 45 tube amp.

At $1,500 including tubes, this was an easy purchase for me. Prior to this time, I had avoided using a 45 tube amp since finding a good pair of single driver speakers was the most difficult thing to do and I was using speakers between 90db and 95db efficient. Not this time around since I now have the perfect speakers and they’re 101db efficient. I’ve been looking for these for a very long time. More about the speakers later on.

I paid retail just like you do for this amp and was just a normal “customer” in the beginning. However, when I shared my last 2A3 amp build with Alan, he immediately wanted me to build a CNC chassis for his own 45 tubed amp build. I designed his chassis and provided my CNC source and gave him an array of high end parts to do his own build. He sent me the vintage Tamura transformer set that he uses in trade for the things I sent to him.

Alan has been building amps for 50 years and maybe has another 5 years of building left. If you want one of the best sounding low watt amps at the most affordable price, contact Alan and order one before he quits building. I don’t receive anything for this recommendation and never have done anything in this profession to make money. I’ve always tried to provide something that others can use and have built my own things in the best possible way. I’ve spent all of my time and money doing R&D because I love music and used to be a professional jazz piano player. Now, I just build components to re-create what others are playing.

I built my own upgraded 45 tube amp design using Alan’s circuit design and his Tamura transformer set and am amazed at how good my system now sounds. It is the best audio system I’ve ever built or heard and I’m so pleased with this exercise that I’ve quit building all OEM components that I used to offer. Instead, I’m focused exclusively on this one component – my extremely upgraded version of Alan’s integrated 45 tube amp. You also don’t need a preamplifier with this amp if you want to achieve the best possible sound quality for the least amount of money spent.

It definitely was worth my spending over $6k on just the parts for this upgraded build versus the $1.5k to purchase Alan’s completed amp. You on the other hand, can purchase his $1.5k amp and then wonder why you’d spend $3k on something like the Decware 25th Anniversary Zen tube amp instead. I think you will be pleasantly surprised.

The Decware amp costs twice what Alan charges and the wait time is at least 2 years (possibly more). In all honesty, I love the 45 tube rather than the 6DJ8 type of power tube that Decware is building. I do have one of their 25th anniversary Zen amps on order just to find out what it sounds like. I ordered mine in October of 2021 and probably have another two years before I see it and can actually do a proper comparison. I might even cancel that order and just move on. The wait time is unreasonable.


Contact Alan and inquire about his 45 tube amp. I’m sure you’ll be pleased you did and I think it is a better alternative. Alan’s email address is located below.
