Good luck, @yuhengdu_tiger . You have a beautiful amp. And your 2 sets of tubes should work well together.
🤞 fingers crossed.

VAC 70/70 mk3 tube rolling question
I recently purchased a VAC 70/70 mk3 s. Where can I find more information about the tubes diagram for the amp? I know it uses two 6sn7 per channel. Are there any differences in functionality between the two 6sn7 used for each channel? For example, do I need to use a matching pair of 6sn7 per channel?
I have one matched pair of RCA red base 6sn7 and a matched pair of Raytheon vt231 6sn7. The RCA are good for lush mids with 3d soundstage and Raytheon vt231are good for speed and accuracy.
They were meant to be used for the Schiit freya plus which uses a pair of 6sn7 for output stage and another pair of 6sn7 for voltage gain stage. Now since I already get a VAC renaissance 5 preamp, I am wondering if I can use my two pairs of 6sn7 on the VAC 70/70 amp.
My question is can I use one RCA + one Rayheon vt231 for each channel of the VAC? Or should I use a matched pair of 6sn7 for each channel? What are the recommended settings?
Also, any experiences about tube rolling on the VAC 70/70 mk3 are welcome. Like which 300B amps or 6sn7 combinations give you the best results.

@lowrider57 Thanks! I came across this ad https://www.canuckaudiomart.com/details/649558669-vac-valve-amplification-company-renaissance-7070-mk-iii-mint/ and by checking at the pictures my best guess would be that V1, V4 are phase inverters and V2, V3 are gains. |
