Thanks worked great. I'll tell ya the split turretts are VERY enjoyable to work with. It's also easy to do a nice neat job with them!

Tried downloading the instructions this morning, and it's a no-go......it starts, but stops at about 850Kb.
Same with the 50 watt instructions..no-go.

Did you get the file? I tested it and it seems to be working. It's a big download, it will take some time.

Ok I think I'm going nuts, I cannot see an instruction to attach the 1K 2W resistor to either the board or the output tubes. I mean I know where it has to go, but its driving me crazy

Are you positive that it's a 2 watt resistor? They usually include 1k/5 watt cement resistors in most kits for the power tube screens. They are soldered across pins 4 and 6 of each power tube socket with the feed wire connecting to pin 6. I'm not sure where a single 1k/ 2 watt may be needed though.

Some amps use a flying 1k resistor from the turret on the B+ line from the choke to V4 instead of a yellow screens supply. I have it on both my 64 and 65 JTM45s, only brings screen V down a little extra but in these amps sounds spot on.

Gotcha... I really need to build a JTM 45 one day soon. It's the only circuit I haven't tried yet. :thumbsup:

Here you go. Valvestorm has a good link at the top of their JTM 45 build checklist page.

Hi George,

I have a JTM45 which I wish to install the ZL-FX board I recently purchased. I see links here to instructions (web link and a dropbox link) but both appear to be not working. Can you point me to these instructions ?

Thanks in advance,
