Speaking of Harp mods and such - I recently had a "Harp Modded" RI Bassman amp in my shop which had 12AU7 preamp tubes installed in it. The result of this was that the 1/4W plate resistors had burned and become out of tolerance & noisy. Something to be aware of when blindly swapping tubes - the voltage drop across the plate resistors and cf cathode resistors can become excessive and cause damage to your amp.
