my experience only in this amp:I am considering trying the EH 6ca7 power tubes. Also, the Genalex KT-77. I have read a number of threads concerning these, but few mentions of the DSL40C. Anyone here listening that can provide insight into what to expect. The 77s are way expensive. I would dislike spending over $200 with tax on a pair of tubes and not enjoying the result at all. The EH tubes can be had for under $100 with tax. I know that this can be subjective when it comes to tone, but I have used the opinions of others on this thread to make positive changes with my amp. Thanks.
no on the Genalex KT-77. For me was not a sonic upgrade in tone or feel. In any of my Marshalls. I spent the money and found the truth. Done.
EH 6CA7's- added articulation while soloing nice raw animalistic bottom end.lol Great power tubes. Have used in a few of my Marshallz now.
I play at volume. Only way I like this amp. It opens up when the power section comes on. Otherwise you're just hearing preamp. I still love playing this amp. Broke it out today after a long hiatus. Threw in a Veteran 30, dropped in the original 34's which hadn't seen much play time and of course a rebias at 34mv. Tits! The fuker sounds and feels great. Only reason I put a different speaker in is I'm playing musical 12's in my Iconic 412. Don't like the 412 stocker's any more. Too smooth for me.
Daem if it ain't the heaviest combo I've owned! I originally bought it for an easy grab and go jam amp. Boy was I overestimating my strength.
