Replacing 811-A tubes with Penta 572-B tubes in an old Heath Warrior - I have heard new
parasitic chokes should be built and installed but don't have the information other than
"the minimum inductance that will stop the oscillation with non-inductive resistance in
parallel." Has anyone out there got some 572-Bs in parallel with chokes designed by the
amp manufacturer? IF so, would you please describe how they are built?

Thanks !
