ODS plate resistors and cathod bypass caps

[flatart]

I'm building a ODS 50W clone and I would like to know if someone of you have already experimented with following different solutions:

- preamp plate resistors should be 100K. However many of the later amps with the Skyliner EQ have 220K plate resistors on the preamp tubes.

- The clean stage has 10uf bypass caps across the cathode resistors, while many of the other ODS amps had 5uf capacitors.

a feedback on this would be really appreciated
thanks
