Can any of you see anything incorrect about this circuit for my SSE.

When I built my SSE, I installed a pair of dpdt switches on the back panel for UL and nfb. However, I don't feel like I'll ever need either. So, I want to use the switches to parallel extra cathode resistors. With 910, on the SSE board, if either switch shorts, I'll not fry any tubes. This combo gives me 910 for EL34, 535 for KT88, 713 for 6L6/EL34 and with both switches thrown 461 for KT88 or KT120.

Thanks,
Charlie
