I just finished restring and leaning this Tektroninx 502A, Im still waiting for 3 tubes that it has missing before I can turn it on for the first time after cleaning it,before it just made a dot, so the HV was there and it gaved some life but had missing 3 tubes and a transistor, now I dont think I will found a identical transistor so I will have to substitute it probably ,but its in the power supply so I ques it shouldn't be that complex
the missing transistor is a 2n214, with wat could I substitute it ??
Im planing on using this scope on vintage tube amp buiilds and stuff ...

Full time amp tech here.
NTE103A transistor will do the job.

If you're building amps, you wont really have much occasion to use it. I only have to fire up my scope to track down parasitic oscillations. Do the filter caps while you're in there replacing the transistor. Cool piece of equipment you have there.
