Nuvista tubes - need a tester or adapter

Aren't those Nuvistor tubes? Used to find those in TV tuners of lore. Might try rec.audio tubes. Some of those guys are pretty sharp and may be using nuvistors in audio amps.

Musical Fidelity make a nuvistor preamp (called 'Nuvista' oddly enough). I think they bought up just about every NOS example in the world to be able to keep making them and supplying replacements. I had to get a new set in for one that I had in for repair a few weeks ago. One had gone microphonic, but MF insist that you change them as a set. The shop that I was doing the repair for actually got them in, and I think they were around eighty odd quid for the set of four. There are plenty of schematics on the net for nuvistor based amps, and lots of data. I'm sure it wouldn't be difficult to cobble together a base for one using something like the sockets stripped from a turned pin IC socket set in a bit of PCB material, or even MDF and hard wired at a pinch, and then to knock up a little circuit that characterised the basic operational parameters for the device. Even an actual preamp to test it under 'real' operational conditions.

John, I have a Hickcock tubetester and can test them for you. Email me, my address isn't bunged.

My 60s era Navy Surplus tube tester has Nuvistor sockets.

Thanks for the offer but we found nuvistor sockets and will make an adapter for the tube tester.

Thanks to all for your help.
