Hello Eric and Rob;
I can't brag about a great cleaning job on my 505 'cause I only wiped it out with a damp cloth. I did recap it, except for the HV deflection caps that I have yet to aquire, so it is not up and running. Rob, great idea using that bug zapper supply! (Just on that thought, wouldn't it have been fun if Frank Zappa had named his son Bug??) Sorry, I digress. My Halli has the old tube complement, and my sams the later. Not sure but it sounds like there are two versions of the sams. I paid a fare amount for this set, but found the Mahogony version for $5 at a yard sale! That one was, and still is kinda rough but at least had the magnifying lense mounts. Eric, where did you get those knobs made? I have different sets going knobless. No, the bass drum it NOT some sort of newfangled antenna!
