TU-8233 with 45?

[astrojet]

Hi all.
I'm wondering if anyone has ever tried to mod the TU-8233 for type 45 output tubes instead of 2a3. I guess this would be as simple as swapping a few bias resistors. Perhaps it could be improved by subbing OPT to something with a little higher primary impedance. Any thoughts?
Thanks!

The new 300B amp will be available in September..
This amp is the big improvement of TU-8300R.

Do you have any information on this amp? What's the model number? Cheers.
