content: Quote from: McBryce on July 14, 2015, 11:49:13 amIt would be cool just to own *one* device like that, just because.(And that one is a good candidate).What's the green display thingy on the left, about half way down? One of the photos shows it lit up.I've just asked him about cheapest possible shipping to Spain (if you're the seller reading this: Yes, that question was from me!)

content: What a beauty! I wish I could justify owning it. Love the Geneva-type interlock between Q and D dials - simple, functional and obvious.

content: Quote from: McBryce on July 14, 2015, 11:49:13 amYeah, but they have a ton of tubes in them and I guess the three HV tubes (the 240 and the 240A are *very* different designs. The 240A is solid-state except for a single HV pentode) will be unobtanium by now.

content: There's a 240 (non-A version) on ebay at the moment for about €6. One went a few days ago for about €17. I've no use for one either (and they don't look as impressive as the devices above, rather boring actually).McBryce.

content: I had an old Heath I decided to fix up and see what I could do to improve it without drilling any new holes in the case. Made the supply solid state so I could use the triode rectifier as a gain of three amplifier for the signal, zener regulation on the eye tube display and low voltage leakage, protection for the pot from charged electrolytics. I sold it as an upgrade kit for the Heath C-3 on ebay with capacitors paralleled to better than 1%. It was quite a nice package, sold a lot of them, but it was still just s C-3. Don't know why everybody loved them so much. Some paid $200 for a rebuilt one.
