I posted a notice about a month ago in that i had scored a box load of 300s 845s etc.
I also have a pair of 5k potted transformers, a very hefty power transformer that needs a new home, and the wherewithal to build a nifty amp.
So it's time that something came of the assorted bits'n'pieces that I've got kicking around.
I'm fairly relaxed about design, and can design my own drivers.
What I'm generally interested in is the general merits of a couple of design options that I am tossing around.
I like the thought of driving the 300s with either of the following,
1. a power drive cct a la tubelab, or
2. cathode follower.
The 300B as i read it, has quite a bit of capacitance to overcome, I also like the idea of moving into A2 as well, hence the need for the above.
When it comes to the bits before the above, a couple of schmitts? or a simple two stage with a concertina or single stage then a concertina then a driver?
I've also got 10 IXYS 900V CCS devices, that I am keen to play with.
The options, the options?
Any thoughts and ideas most gratetfully accpted.
sorry if this is a ramble. Just looking for ideas, I've been searching the web for cct diagrams, there are dozens all seem to have their merits, interested on hearing other peoples ideas before I commit to far.
