Can someone tell me what stock pre-amp tubes are in the HT 40? I see the power amp tubes are Ruby 34's, what are the ECC 83's? I just want to order a set to throw in my case in case of a bad tube at a gig. I don't need to upgrade, I'm happy with my sound and just want a factory set to keep on hand.

Since you have Ruby EL34's, you most likely have Sovtek 12AX7WA/7025's in the preamp: https://www.tubedepot.com/products/sovt ... acuum-tube
