Hi Bruce:

I am in the process of working that out. Depending on what you want, the costs will vary as I made the system modular. More information to follow as I got a system completely wired and put into a project box. I need to post those photos as well.

Regards,

Gerry

Here is one unit finished. Ran for over 24 hours under load without any issues.

And last night I managed to borrow a 4-tube farm radio that uses 1.5 V for the filament and 90 VDC for the plate. Hooked up the power supply and no issues! This is the last acid test for the unit – I am making plans to present it at our local meeting in Edmonton this coming December. And there will be a follow up article for the newsletter. Cheers!!!
