I just bought a used JVM205H with a blown PT. Anyone has one to sell? Mercury Magnetics has the tranny but it's speced for the JVM combo and its PRICEY. Thanks.
If you play the amp at low to moderate volume levels you won't notice that much of a difference of having a choke in a DSL40C. In my case, the choke mod is an advantage because I play a lot of metal..and loud. Loud meaning anything past the 12 o'clock position. The bottom end is much...
If you're comfortable with modding, you can install this in your DSL15.

I have a similar one on my DSL15 made by another company. It's working great so far.
I clipped C4 and C5. The result is cleaner, warmer Cleans and Crunch.
It also balances the level between the two modes. Couldn't be happier. Try lifting one leg of each capacitors first and see/hear how you'd like it.
I've been gigging with my 5150III three times a month since I bought it in August.
I replaced the 6L6's shortly after with Gold Lion KT66. I'm liking it even more. The KT's gave a hint of EL34 chime to the tone. Yes, the PT can handle the extra heater current of the KT66. :hbang:

Hey Marshall Dog, I have tried Genalex Gold Lion KT77. What I've notice is extended highs and bottom end. Brittle but not crunchy, bassy but not punchy. It wasn't that pleasing to my ear. Too hifi to me. GL KT77's sound great on my 6100 but not on the DSL40, don't really know why!!!
EL34...
I did try out of curiosity. I would do the opposite (i.e increasing the preamp voltage instead incl PI) but there's not enough room to increase as they are already close to maxing out. Besides CP tubes probably won't last above 300+ volts anyways. No moola for NOS.
Lower voltage to the preamp tubes will increase the overall gain but you will also lose headroom. It makes the amp break up sooner giving you the "brownish" sound. The mod definitely works great in 2204. I've done similar mod in my 6100 but I would not recommend this in DSL40C. The amp will...
