Take care which pin are you decoupling.
Silver-mica cap must be in same position as the 100nF cap (near to XO) in below Tentlabs picture.

The parts I use for modded power supply.

Instead Soft recovery diodes MSR860 proposed by Peter Daniel, I chose to go for Silicon Carbide Schottky Cree CSD1060A. To my ears these offer a smother and more fluid high register.

The power supply board offer the option for two regulators, standard LM7808 and LT1086Adj.
Beside lower noise and excellent current capability, I got more detail with LT1086Adj, so this is my first choice here. LM317 is out of discussion here, performing under standard 7808, so don't waste your time.
As Black Gates are history, for primary 2200uF cap my choice is Panasonic FM decoupled with an oil cap. I used Russian PIO with great results, but new Mundorf EVO series are quite amazing, compact and performing very very good. Any HF spikes and noise are very nice cleaned.
You can get them from partsconnexion. Very good value.

For output cap my choice was Elna Cerafine decoupled with a 1nF silver-mica. The cerafine will provide excellent low esr, stabilizing LT1086 regulator, while 1nF silver mica, with his ultra low ERS/ESL, will clean further any HF noise.

IMHO this is the most cost effective power supply who will sensible improve your Shiga MKII.

What is the value for the four SMD resistors ?

thanks
