In an earlier post I said if you don't turn the amp on every day and leave the amp totally off for a few days the 274 tends to arc, having something to do with seeing a higher value cap in the power supply. Makes sense since the capacitors do charge down after a couple of days.

Will and Lon Thanks for the RCA 5u4 recommendations, and the GE  6BQ7 in another post by Riveiraranch. try these together.

I have gone back to the MIC made in china 5u4 with no acring. so back to the SE84c+ tubes in my superzen and all Decware amps I have. Safe common sense choice, even in the Racheal, El34's of my own choice. seems the best compromise...
