Thanks for the replies, guys.
Actually, I retubed my VHT 2502 on the day I got it with JJ EL34L and ECC83S. Since JJ tubes haven't let me down in terms of sound , I just retubed the VHT right away before trying it with its stock VHT tubes. I figured that it'd be a hassle to install and re-install power tubes anyway, unlike preamp tubes. :dance:
