I'm thinking a Bias and an added depth control with a 5751 in one of the preamp spots might be the ticketYea i went down the rabbit hole on modding my HD100 and honestly it was a fun lesson but a good set of tubes, biased properly is all you really need to do...
The amp already has good tubes, bought it used with Sovtek 6L6GC and JJ across the preamp. Maybe a Tung Sol in V1 and a 5751 in whatever the next spot that affects the overdrive channel is might be a good start and maybe all that's needed.
