I ran my stock Smash for a couple weeks and decided it was time to install the Smashup upgrade. Install went smoothly and it fired up and sounds great, hoping to get some good listening in this weekend but at least know its up and working.
Two things came up that I would like to get some input on:
1) Voltage check on the A socket side of the Kreg/B3 connection is about 5.8V and on Kreg/B6 the B side its 3.8V. Swapped to another 6SN7 and no real change still a bit uneven and above 5V on the A side. Is that being out of spec an issue?
2) Microphonics, these 4P1L tubes are very "chimey" I'm not hearing it while it is playing, but when turning the input selector and tapping on the top plate they ring for 10-15 seconds. I have never really worked with any loctal tubes, is that just their nature? I don't have any to swap out to compare but may see what I can scrounge up somewhere.
Otherwise this thing even stock was quite a step up from my well modded Foreplay. Thanks for a great kit!
