Thats interesting of the work done on the RM-4.
I use to own a RM-4 for about 5 years when it first came out.
I used it with the ARC SP-8 for moving coil head amp
reproduction.As I recall you could solder in your own resistor to load it too the proper value you needed.
Even stocked the unit has a wonderful bloom in the midband
and a very musical unit at that.Roger Modjeski used very high quality tubes with this unit.
The RM-4 is a great find if u can locate one on the open market used.
I have done many experimental mods using Vishays myself
and I'm very familiar what this resistor is capable of.I.E.
A huge reduction of the noise room floor,A very,very transparent resistor,which opens up this vast 3D Soundstage
that is locked tight with perfect imaging around the instruments playing in this soundfield.
I have not audiotioned the ARC Head Amp your refering too
But I'm sure if this was moded out it would sound much better then the RM-4.
Happy Listening
