Cool, I was going to ask yesterday if you got it going. I would be there too, if it wasn't for still waiting for that part. Actually, I did order one from Antique Elec. Supply. Don't know which one will get here first. I know one thing the one I ordered will be here by next Mon or Tues.
I'm glad you like it. I started having "choosers" remorse earlier in the week after reading all the stuff here and ampgarage. I think a person can read too many opinions. I started thinking I should have ordered a different model. (non-hrm vs. hrm) Some of these guys have built many different versions of this amp and it's probably like a parent and their children, you love them all, just sometimes certain ones are more appealing depending on the day and personal taste.
It seems to me that it will be hard not to be totally thrilled when it's your first one.
So have you messed with PI yet? Interested in your findings.
Keep on playing!
