If you can't afford a new one, just build it yourself (I told myself). Trust me, manufacturers earn every penny they ask.....
Almost 12 months to design, gather parts and build a high voltage amp.
This is my third scratch build and consists of a 76-300B-GM70
IT coupled driver for A1 to about 22 watts and A2 to about 40 watts
400v and 1200v supplies which is more than enough to kill
Coleman filament supplies
Custom chassis from Landfall Systems
Arduino control for monitoring, soft start and standby
Sounds like a gigantic 300B amp on my Khorns
