The Valhalla2 is a strange OTL amp, agree with you that its like a SS amp, rolling tubes has little or no effect on the sound from my limited time that I spent with rolling tubes in it.The question was about Russian tubes but I have run Tung Sol etc. and own a Valhalla 2, IMHO the Crack is warmer sounding with most any combination I have tried. The Valhalla is a little tough to discern from solid state or maybe I have not varied my tube rolling in it enough to approximate a Crack.
You have to mod the Crack to use E80CC or 7119 (5687) tubes.My pair of choice is the Tung Sol 5998 + Mullard 12AU7 (Or Amperex Bugle Boy, Tungsgram E80CC , Amperex 7119 PQ -> Crack needs modifications to run the latter 2)
Yeap -> https://imgur.com/a/Ax2VGYou have to mod the Crack to use E80CC or 7119 (5687) tubes.
Amperex 7316 Long Plates Foil Getter is one of the best. But, hope you can find it.
For that price, I will get a ECC33.Yeap -> https://imgur.com/a/Ax2VG
Yeah i was looking for one of those, but as you said, they are super hard to find for a decent price.
Been debating getting a VT-231. Already have quite a few good 6SN7's. But lets see, now a days i usually swap around between the Mullar 12AU7/7119 PQ/Tungsgram E80CC. Sometimes even using the Telefunken 12AU7.For that price, I will get a ECC33.
I ended up using mine more as a preamp out into other amps including Crack amps.
I have used a Crack as a preamp and even added outputs on two of them. I have several amps and amp/DACs with more arriving next week. They do work well in that function; I tend to experiment until I find an exceptional sound I am willing to share with others. My latest interest is balanced amps but I keep all those components separate.
I cleaned the tube contacts, both male and female ends, on my bottlehead crack and it seems to sound even better. I use Deoxit. Am I imagining things?
https://www.digikey.com/product-detail/en/2250-832-AL/1772-1226-ND/So I'm getting ready to mod my Bottlehead crack and was getting my shopping list ready. I've decided on adding a choke, replacing the 2 output caps with film caps, modding the power supply with cree diodes. Anyone got suggestions on what to purchase to mount the choke? I think I've got the film cap mounting and the PCB board down.
