Hi everyone. I hope someone is willing to help out.
I am building a Bob Latino st VTA-120 kit amp. It is based off an upgraded Dynaco ST-70 and uses kt88 tubes. Essentially 2 MK 3'S in one chassis. The original power supply uses a new quad cap with 80,40,30,20 uf sections.
I am building the amp without the quad cap or the rectifier. I will be using solid state rectification and am using Mundorf Tube caps. 3 in total 100uf, 100uf, and 47uf.
My question here is would someone be able to confirm my schematic and drawing to make sure I have not made a error.

Thanks in advance

Since I don't know the current requirements of the amp, I can't comment on the value of the resistor you have added to the PS, but if it were my amp I would replace the resistor with another C-24X choke and a cap right off the rectifiers. So it would be cap > choke > cap > double choke > cap.
For this amp the solid state rectifier used is a weber wz68. The r value is determined by the supplied cap. I have just copied the schematic from the weber site to illustrate ss rectification on my drawing.

As for the choke I dont think there is enough room left on the chassis. It would need to be quite large and handle min. 500mah..
