I’ve had a few different tubes amps in my life. But I had heard rumors of the mystical type 45. A 1.5 watt single ended triode. 1.5 watts? How could that possibly be enough? Then I found myself in possession of the Altec Flamenco’s. A high sensitivity horn loaded speaker from the late 60’s. I tried various solid state amps and even a few push pull tube amps but the Flamenco’s wanted something different. After an online search I landed on the Alan Eaton 45 mono blocks. They had a solid reputation with several positive reviews. I decided to take a chance and order a set. I had the pleasure to speak to both Jason and Alan Eaton. Both were extremely helpful and knowledgeable. They worked with me to build the amps to my specifications. I had a moment of panic after placing the order. Could a 1.5 watt amp drive my 100 pound speakers? Once I took delivery, all my fears faded. These amps are beautiful. Minimalist, and purpose built with vintage parts, high quality output transformers and NOS tubes. They are able to drive my speakers with ease. No preamp needed. Musical and dynamic. Jazz has never sounded so good. These are keepers. I’m very pleased with my purchase. My only caveat, if you’re getting the 45 amps, they do require a highly sensitive speaker. Order with confidence. Hand built in the USA, point to point wiring and the sweet, sweet sound that only the 45 tube can deliver.
