Title: Help installing choke and OT
Post by: Paul G. on May 20, 2014, 03:38:53 AM
I acquired a set of transformers and had Nik build me a fully assembled chassis, minus transformer and choke.

Now I can't figure out how to install the choke and 1 screw on the OT without pulling the turret board and messing up the perfect lead dress.

I can probably get the screws in with wire and fiddling, but if I do, how do you keep them from spinning as you tighten the locking castle nut?

Any help would be appreciated here!!

Thx.

I assume you mean keps nut, a castle nut works with a cotter pin.

So, you want to put the screw through under the board and then use a keps nut on the outside of the chassis? Simple, add a lock washer between the screw and chassis. It'll eventually grip the screw and keep it from turning.

Thanks for the response. In the end that is exactly what I did. I went to my hardware store and found a shorter M5 screw, a couple of lock washers and matching non-locking nut. It was fiddley fishing the screw in and took a while to get it to fall through. Once it was in place, I gently started the nut. As soon as the nut contacted the bracket the lock washer started to bite and all was well.

Brillant!

I mean, what else could I say about it since it was identical to my solution.

Hope the amp is awesome.
