My Holton amp builds.

[Leikis]

Both amp boards mounted to the heatsinks and one of the capacitor banks soldered.
The aluminium rods is to hold the cap banks without the bottom plate so i can solder the power cords to the amp boards from the underside.

Thank you Anthony.
I must confess that i was just built your amp... Tried it technically and hear some music trought my small test speakers for safety reason from past. Because of abssent from home i can try it seriously in next days. Btw. Modules are very good production quality and smart design. Assembly is quite simple even for Diy members with less electronic skills. Almost no soldering, just plug and play.
Nice greet Davorin

Amp in action. Sings really beautiful. At bias set to 360mA, it plays extremely rock stable, full and wide in all dimensions.
Everything is on right position, very fast amp but not harsh or thin sounded, more on soft side. Very satisfied. I have done 2 version from FO (1.2 and 1.3) amp, and try it at my place but this amp is much more musically to my ears. More fuller sound more realistic timbre, and not so dry sounded. Excellent design.

Thats Awesome!
Thanks so much for posting your experiences.
Once again beautiful job with the build of the amplifier.
