I've seen these in the flesh; when collecting bottles from Gerry.
Very impressive. |

Re: BIG AF amplifiers!

Re: BIG AF amplifiers!
There were some Russians at the Genova fair today selling TY81s for 20 Euros each. They only had one wierd (abortianate) looking socket though.
It was hard but I resisted, now I'm starting to regret not getting a couple of them. Mike |
