Out of interest is it a teddy cap you’ve used on the SN2 I have one which I love and am interested to try a psu though not a HCDR at £1000Thanks @kimbleman , I'm torn on this one tbh because it is just such a cracking amp and with an external PSU on it (I favour Teddy Pardo) it really sings! I'm in the process of going to 282/250 but it's a lot of extra money to spend and the SN2 is proving hard to part with. Half tempted to keep it for a rainy day, but that just seems such a waste. First world problems and all that but doesn't make these decisions any easier sometimes.
