Default Re: Tektronix 585A issues.

Thanks Ian, That's a very kind offer, will drop you a PM.

Checked the scope over yesterday and it's working better than it was before it went bang. Still haven't found what caused the original fault, it's a puzzler.

Re B171 & B167 can anyone confirm whether they are supposed to be lit at the same time? It looks to me like they're there to keep the grids of V173 at 60v. On my Hickok 545 clone they're both lit AFAIR.

Curiosity hasn't killed this far.
