Very nice looking. I like it. You should make up a name for it and patend it!
Might be able to sell it and make millions.

Here is an image of the 300B amp (Silver Dragon) with PS. The amp and PS weigh 15kg each. I had the power tranni wound locally. Though huge it still gets hot. The amps draws 90mA per 300B at 435V.

There is a dual secondary Hammond filament tranni in the PS. This is rectified and regulated for the 300Bs. There is no electrolytic caps in the PS they are all Mundorf M-Caps polypropylene: 3 X 47uf and one 100uf. The TJ 300BSE tubes have an RRP of $1200. I have two pairs plus a pair of Shuguang 300B-Z 50 Year Treasures. The driver tube is a 6SN7 Shuguang 50 Year Treasure also. All tubes are ceramic base and gold pin.

Default PL300PP

Almost finished, PL300 sweep tubes in push pull.
Gives about 36 Watts per channel, with a nice firm bass.

Now it's time to make a transformer cover, and clean up the bench

My latest digging-through-the-junkbox-project: 807 PP UL with 6SL7 LTP input stage and GZ34 rectifier. Edcor 15W 8K/8R output transformers, Hammond 300-series PT and a 10H 200mA choke from vt4c.com. The power transformer is a bit underrated and runs quite hot after an hour or so while only producing just over 300V B+. The amps sounds just fine, nothing special but fine.

Do you have a circuit, what voltage and out put transformer impedance did you use?
i am hoping to make a 6CB5 pp amp; going by posts: i think would require about 400 volts.
thanks
Phil
