Looks good! But You You took many solutions for non-existent problems, I will try this Solidworks mock-up software, Does is friendly or/and intuitive?
Best Regards.

Solidworks. $4,000 USD for standard edition, when you need it to pump out that IGES file (and many many more), there is no comparison. I had to use this for the parts and moulds I used to sell because it was industry standard.

There are alternatives.

This is what I like to see!
A proper built and functional!
Very inspirational!!!
We need to see more of his kind of build please!!!!!!!

I can't stand it anymore when I see extra " thingies" on tubes amps. If they don't serve a purpose, don't put it on there...

Sorry for a mini rant!

 

[tim614]

And the tranny behind the bunker?

Yeah, what's behind the bunker thingies ? Choke?

Whoa! Is output power in kilowatts?! As far as I can see the meter readings.

 

[dady]

If this is the preamp, how is the amp?
I never hear before about this 307A tube. Which topollogy use with her?
Is possible similar to 11e3 english one?

That's probably the choke for the CLC supply filter.

Hi! What do you mind PSE? Push-pull SE? No,just 845 driver push 845 output tube.. Pout=24W

845,
THey look stunning. I have 845 tubes, high quality OTs and a 1050-850-0-850-1050 Volt power tranny rated at 300mA sitting on my shelf. Would you be prepared to share you schematic?
Perhaps you could start a new tread if so.
Cheers,
Ian
