Obviously ;)
Actually not such an uncommon mistake among DIYers. It could have been rather catastrophic without the CCS (LM317).
But why 6SL7? I thought we had already explained that you cannot use the 6SL7 in RH84 rev2, but you might use 6SL7 in the RH Universal if Rfb is set (by switch) to ECC83 adequate values (200k).
Though, the 6V6 is not adequate for the RH Universal, too low anode dissipation... so, what hybrid RH schematics have you applied to your amp?
