The Admark AD42 is not crap, it is value for money. I'd like to see which European/US lightweight, matches he Admark AD42 in performance, for only twice the new price.

Found this, changing the channel board on the right hand side. Interesting.

I have mate in West London, prob 1/3 electronic engineers in London, who specializes in servicing/repairing these. He charges £600, to overhaul Admark amps, fixing manufacture shortcomings, upgrading cables where needed, replacing solder joints where needed. He has well known Reggae sound, used to design and build his own transformer amps, previously owned Powersoft K20.
He now has Admark on Mids and tops. Edited by levyte357- - 16 October 2025 at 6:44pm |

Yes, except, when you have an Engineer, quite experienced, with opening that particular box of chocolates, and replacing the orange flavored selection, with mint.

here's another shot which shows slightly more of the internal. Spec says it weighs 20kg so it's not just a lot of empty space inside the case. Can't see the value of the caps but looks like substantially more than you see on some other 4 channel amps.

similar internal layout but in 1U and 17kg. Caps look like they are 680uF
