My recent Dizzy build came before Nik made the layout switch from the Matchless crossline ppimv to the now shown LarMar ppimv. I had been reading up on the LarMar and the Hall Amplification vvr trying to decide on which to stick in the original master volume hole. After input from Psamm on his recent dizzy build thread I decided to go with the LarMar. Having used the original mv for about a month and mostly having it disabled I find that the LarMar is a vast improvement. I may put the vvr in someday but on the other hand I'm so satisfied with the LarMar It may not be worth the extra effort.

I ordered my 250K dual ganged audio pot from tubesandmore.com. It was pretty out of spec and unbalanced as well. 230k on one section and 236k on the other. I used two different sized resistors to compensate and all works well. I had ordered some nice little 2m2 carbon comps for the job since the rest of the amp uses them but had to use some carbon films that I had on hand since the pot was wacky. If you attempt this install it would be best to source a higher tolerance pot for the job. Now I just need a head cab to give the baby a home.
