Congrats on your purchase Joseph! Looking forward to your impressions - I'm really interested in your thoughts once you've had a chance to compare the two amps for a while.
Glad I could provide some opinions and hope the SE delivers for you.
Make sure you check the tube list on Woo's site for the SE. The vast majority of what you have will work, but a few that are compatible with the 6 can't be used in the SE.
I was looking at the tube chart, and the way I see it, I could use every tube I have… but the 6SN7 from what I understand from the chart says the WA6 (needs) an adapter (which I have), and the S/E (doesn't) need the adapter. I asked Jack about this and he said the 6SN7 should NOT be used with the S/E (which is a favorite of mine), so I'm really not sure if I can use it, because the chart says I can (without) the adapter, and Jack says no. Do you use the 6SN7' in your S/E, or anyone for that matter?
The 6SN7 is, unfortunately, not compatible with the SE. I don't remember reading about anyone who tried them in the SE and I got the same response from Jack that you did so I won't be.
I'm really interested to see if you like the same tube combos in the SE or if you find new tube pairings you like with the new amp.
Hopefully the wait for delivery isn't too long.
