6SL7 SRPP to 2A3 direct coupling

Hello,

I was considering building this amplifier: 6SL7 SRPP / 2A3 Single-Ended Tube Amp, but, unfortunately, I could not source a proper power transformer.
I would give a try to the easy to find Hammond 302AX. With this in mind, I came to the following schematic:

and this would be the power supply:

Since this is my first time messing with a schematic, I would like to know if there are obvious mistakes in my calculations or if you have any recommendations for improvement.

The output transformers would be Tango XE-20S, the 2A3s would be the Linlai 2A3T and I intend to build two monoblocks.

My speakers are the Klipsch RP-280F, with 8 ohms and 98dB.

Also, in subjective listening to an amplifier, would you go with this SRPP driver or with a more conventional approach like the Shishido for example.

Thanks in advance for any opinion!
