Tex, I was reading on the Gaggia group stuff, and there are four mods typically talked about...the OPV, the SPV, the steam wand, and the PID. Correct?
I have already done the Silva steam wand, easy.
I have a Gaggia Classic, so it should have the adjustable Pressure valve correct? I just need a gauge with which to measure and calibrate for 9bar.
The SPV on my Classic doesn't have the little ball valve thing to mod...should I replace the SPV altogether and do the mod, or just leave it as is. (I have
THIS ONE Should I replace it with
THIS ONE and mod it?)
The PID, I haven't started that yet, but I forsee no issues.
