Parmeko Valve Amps - Direct Coupled DA30 SET

Single ended triode amps.

Home built valve amps stuffed full of Parmeko transformers and chokes.

Parallel single ended da30 amps designed by the eccentric Noel Bonavia-Hunt
Direct coupled so around 1000v HT

Unfortunately came to me without  the DA30 output valves (so pictured here with some PX25s)
Vircuit diagram included

The DA30 valve bases have been cleverly modified to be sprung for anti-mixcrophonics.
I believe these amps were demonstrated a few Years ago by John Howes at one of the BVWS meets playing through some Voight horns.

Quad II (not included) is shown in one photo to give an idea of scale of these beasts.

These weigh over 50 kg each!
