Do you think that posters can withold from quoting the previous post if it contains large pics, like the last example? I find the multiple repeated pics confusing.

Hmm, a remarkable likeness, yes! Heatsinking looks a bit better on the RDL. It looks a lot cleaner too. This Hz has had its front panel hand painted around the gold lettering with what looks to be black gloss Hammerite! It was given to me to look at by a colleague and may or may not have a fault...

On that Dunlap Clarke Dreadnaught, the switch on the back marked “Max off Min”. Does it switch transformer secondary windings to give different power outputs, like the old Midas Cube Monitor Amps?

No the switch is for the fan on this amp, you can adjust the speed or simply have it turned off
