Fine, but a pain to fit and use effectively the Tat case that came with the stuff from another member. It sounds great as it is but I don't have a original to compare it to. Lundahl all around.
Yes no on the kit, The kit would add a DI and address the front panel switches phases etc... But it would not provide the +48V. I used a 5 or 10VA toroid and a SSL9K PSU with only the +48 side stuffed, but there is plenty of options.
The switch layout in the PDF is fairly confusing. To many options and not laid out in a consistent and logical manner. I have a few notes that would be helpful for those with Tat's case on how I got it to work.
One more thing in regards to the DI, I'm no expert but you may want to look into the best type for use with a tube circuit. I left the jack unconnected for now, but I may look at one of Owles Fet DI's as a option.
