I am getting ready to build adapter boxes for the double triodes. My thinking is to build two boxes, one for 6-volt tubes, and a second one for the 12-volt tubes. In this way I can keep it simple and eliminate the switch.
So.... I have a few questions for those of you who have more experience with projects such as these. First, I need to buy a 9-pin socket. It appears that there are two types, one for circuit board mounting and one for chassis mounting, so obviously, I need to buy the latter. But I do not know how to securely mount these sockets onto the box in such a way that they can sustain the considerable stress of inserting and removing tubes. Some have mounting flanges to allow the socket to be secured with screws, but I don't know I can use screws with a plastic box. Looking closely at Artsi's box, I don't see any screw heads, so I do not how know his socket is mounted.
Also, I notice that there are gold plated sockets. But I am wondering if it is harder to solder wires to gold-plated metal?
And what kind of connecting wire would be best? Solid core? Stranded? Gauge?
Thanks!
Was thinking also about how to mount that 9 pin socket so it doesnt come off eventually i would go with the chassis mounting socket .i would drill 2 hole for the flange insert 2 screws and and tighten the 2 nuts the only thing i dont know since i dont have the sockets yet is if you can put the flange outside or inside the box if inside looks better thighten nuts and it would be really sturdy only thing you would see outside is the heads of the 2 screws and washers to make it stronger so cover doesnt crack because cover is only .079 thousands of an inch thick which is about 5/64 (.075) so reinforcement would help imo. Heres a picture . Could put socket outside by drilling dia #1 after drill holes put screws in flange holes with nut underside with little lock washers on underside of cover and it should not move .Or if you would put flange inside box cover try to make hole size close as possible to #2 diametre drill holes for flange maybe try and find a big enough washer that would go around hole on top of cover so it looks nicer like rings around tube holes on mk3 as long as tube clears washers inside diametre
