I got the call from Mike B. last tuesday that my IIC+ was ready for shipping back to me. I hope to have it back by wednesday! He left a 2 minute message on my voice mail about what he did. Mine is # 1212* and it came from the factory with the RP11A board. He did the + upgrade ($400) plus changed the caps, and any other resistors that they changed the values for over the years. With shipping, a NOS "Boogie" logo plate, fan cord, new ceramic 6L6 sockets, rebuilt pots, cleaned everything ($237. shipped)... So, I'll have a pretty much perfect Mark IIC+ HRG that Mike B. totally restored for under $1500. So sending that IIC back to the factory isn't so bad at all. Mike B. is the greatest... he'll talk with you about whatever, and will help you get the tone you are looking for.
