@scm I don’t know what Herron uses in the VTPH-2a. He’s pretty accessible. Give him a call.
I keep all my Herron Audio units as-is based on how the Keith has designed and implemented them. If Herron changes his recommended tube complement, I will let him do the rolling using individual tubes he has tested.
I gave you my honest assessment amd experience over the last 20+ years of using VTSP-1 and -2 units. My enthusiasm is just a reflection of my opinion of their performance.
