I LIKE WHAT I'VE BEEN READING ABOUT THE SUN AUDIO 300B PUSH PULL AMP WITH AN INTERSTAGE TRANSFORMER FOR THE PHASE SPLITTER. DOES ANYONE HAVE A SCHEMATIC FOR SOMETHING SIMILAR TO THIS. I WANT TO BUILD IT.
Allow me to intoduce you to the "Caps Lock" key. Please use it wisely. 😉
It isn't all that complex, if it is a SE stage driving a PP stage, you have the driver with the primary in the anode circuit (like an output stage), with the centre tap of the IST grounded, and each side going to a grid.
Have a look at Claudo Bonavolta's phase splitters article. The transformer is the last one on that page.

Not at all sure about the Sun Audio schematics. Here is my main amp. Sounds quite nice.
300B push-pull direct coupled driver amp
Looks pretty nice too:

Google for Ralph Powers PP 6B4G
This is exactly the ckt to use and will work just fine with 300Bs.
Rather than use the Lundahl LL1635, you'd want to buy a Lundahl
1660/10 and then strap it for "Alt V" SE to PP. The 1660 is better
suited for this application.
I built an amp for someone using this transformer. In my case, I
used an ECC99 driving the Lundahl driving PP 2A3. You can use
the 5842WA or the 6C45 with this part. All three tubes are an excellent
choice and the results are very, very good! The transformers will cost
you $200 for the pair, but well worth the performance and ckt simplicity.
