Sounds like the calypso is unreliable with the stk tubes. This is a common issue with all Aesthetix products. I had the same trouble a few years ago with an IO that I promptly returned to the dealer. Don't get me wrong they sound very good, but is it worth the trouble. Products at this price range should work reliably
The herron is totally reliable and sounds good with the stk tubes.
I suggest you have a listen to both to see what you like
