Thackray hybrid tube/solid state Class A amplifier

(1/2) > >>

Just sitting here listening to my friend John Thackray's new class A tube/ss hybrid amplifier that he designed and built. I can't believe how good this thing sounds through my KEF LS50s. Being a class A design it runs pretty hot but that's just the nature of the beast. Trying to get him to sell them as finished boards for using "as is" or for mounting in the end user's choice of enclosure. Two thumbs up John!

Let's have some pictures, the post worth nothing without pictures !!! :)

BTW, please compare the sound/ presentation of this amplifier .vs. your Benchmark amp.
Thanks

Here is the prototype I've been listening to. It's sitting on a small wooden board. You can judge the overall size by the12AU7 tube. I believe John is going to re-lay it out with I/O terminal blocks and make it a little more easy to fit into an enclosure. It's powered by an external 24VDC 5A power brick. It's 6W of Class A which even though low, sounds impressive. Surprisingly clean and a very solid bottom end.
