WAD 300b Parallel Single Ended

[david]

Does anyone know if WAD ever made one of these?

[Greg.]

Yes, they made them as monobloks. A few months later they brought out a push pull version.

The one I've been sent a photo of is a stereo, similar to the 300b push pull stereo. I think it must be the 2A3 PSE, with 300bs in place of 2A3s. Were 300bs drop in replacements on this amp? 2A3?.jpg

[Greg.]

That is the 2A3PSE kit. Input valves are 6SN7. 2A3 heater voltage 2.5v, 300B heater voltage 5v, so not drop in replacement.

Thanks Greg. Someone clearly modded it!

[Ali Tait]

Ive vague memories of someone performing such a mod many moons ago.

Still have a pair of 300b pse’s. Good amps.

Indeed, Ali. You of course, I hope, will have disregarded my Micky take of you about this amp several years ago at Owston. It was just a bit of fun, honest!
I do however hold reservations over the later PP version. I think the same mains Tx’s as used in the PSE mono’s was used and that was a bit of a compromise that impinged on good sound quality. A bit of a shame really but was probably an indicator that the golden years of WAD was starting into decline.

Lol, all in good fun mate. :-)

I mainly keep my pair for sentimental reasons, they were the first valve amps I ever heard.

Indeed, but I wouldn’t invest in it. The build looks good and completely standard. The gold plated Tx caps and faceplate IMHO look scrappy and I have no doubt these amps have had a period of storage in a damp environment owing to the chassis rust and corrosion on the screw heads. £900? He’s having a laugh. £600 might be more realistic.
