FS: Two monoblok PP 2a3/300b all-DHT amps, UK

andyjevans · 8th March 2012, 02:46 PM

For sale, London UK. Collect or can post to UK or possibly Europe.

Two very nice high specification monoblok push pull 2a3 amps with all DHT tubes and DC filament supplies for each tube. OPTs are O-netics as used in Lynn Olsen designs, which these amps are based on. Lundahl interstages. Modular top plates allowing for flexible configuration of tubes. Heavy 4mm aluminium chassis.

Could easily be converted to PP 300b monobloks if that were desired.

Looking for £850.

I also have a similar PP2a3 amp on one chassis with O-netics OPTs - open to offers. Again, could be modified for PP300b.

Are you getting about 12-15W or so? Any pics/sch?

I will have to take some photos over the weekend. I'm not sure of the output - haven't calculated it.
