Turret Board assembly and mounting



Here is the front of the board. I used some really cool components thanks to advice from many of the guys on the Metroamp Forums. The signal caps are N.O.S. vintage mustard caps. The electrolytic caps are BC. There's a cool little Lemco ceramic dogbone for the 47pf cap. The dark brown resistors are Allen Bradley N.O.S. I am really psyched to get this amp up and running!





I decided to get the board all wired up. Here is the back of the board wiring. I have not checked it carefully yet so don't copy this!





I wired some of the grounding points on the amp. Keeping everything very neat...





I replaced the carbon film resistors on the input jacks with some carbon composition - they are supposed to have a certain magical mojo when installed in certain parts of the circuit. I am not bucking any trends with this amp. I am using what has been tried and true.





I soldered some of the components onto the turret board. Here it is just placed in the chassis. Man, this is going to be a beauty!





Here is a pic of the stand offs bolted in. I am ready for the board!





I use plenty of loctite and a 1/4" wrench to tighten the standoffs down.





I am getting th chassis ready to install the board. I don't really care for the small stock board mounting hardware so I am using 6-32 .5 inch stainless steel stand offs. Here I am drilling out the chassis for the larger diameter hardware.
