It's surprising to see these amps getting the full commercial treatment. The original design apparently came about because JLH was considering moving from his Williamson Mono Valve system to Stereo, and decided rather than build another Williamson he would try the new fangled transistor things. So he designed a minimalist Class A amp. , basically a four transistor design, and to his surprise found it provided comparable performance to the Williamson. He wrote it up in 'Wireless World', and people have argued about how the output works ever since. So compared with modern stuff it won't measure particularly well, modern (fast) transistors may give it indigestion, won't drive stubborn speakers, and won't do loud. And like the Williamson, you can probably switch the heating off. A bit of a cult item. For a more modern 'take' on class 'A' see Nelson Pass or Douglas Self.
Thanks for that Elecifun. That is an interesting looking kit. Rock on amigo 🎸 🎶 🎵
Wow ! Sir I must commend you for making so many amps! 🤔

@everTriumph Thank you for the informative comment. I will check out the Nelson Pass and Douglas Self.
Doesn't this kit come pre adjusted. I'm using 21.5 volts per channel.
I made one of these from scratch with local component purchases (Australia)
It tested well and looked good.... sounded crap :(
@cobar5342 sorry to hear that. I will admit I haven't audio tested this one. I will check it out v-soon and get back to you.
Beyond my comprehension. 🤔
@decem_unosquattro9538 Nah it not. Have you built up your amp yet?
@@Elecifun no sir, I'm still renovating my house. Hopefully I can finish it soon and then start on my first amp. 😀
