I know these are going extinct, but I wanted to build one anyway. Converted the schematic to turret board layout, used a surplus stereo box and panel express front and backs. It still astounds me what 4 watts/channel can do; the effort was worth it and I love this thing! see photo:

Hello,

Where did you manage to get 6T9 valves from. For some years now I have been unable to source them (from Australia anyway)

Any help would be much appreciated :)

Hi Grega, welcome to the forum.

Take a look at this thread: WTB: Spare 6T9 anyone? and try the various links. Hopefully some of the dealers have found sources. They tend to pop up on eBay now and then as well.

Good luck and if you find a source, please let us know where.

Cheers

Good luck. I've been on and off checking various online vendors that still have them listed, but an inquiry yields "sorry, we're sold out". At this point, I think you'd have better luck finding hen's teeth. ;-)
