Actually they are totally different in size, I know as I bought some when Gary did and have the old 5n1 for actual comparison.Red to black wrote:I was asking for others opinions on this too
No worries, I'll take the hint and back off now

Large AC currents, will tend to warm the capacitor and can be judged if ok. Large spikes are different, it will just breakdown without warning, some mixed dielectric capacitors common in late 60's early 70's had high working voltage, 1000Vdc but did not like line timebases with the spikes, or across the mains supply.
If you have found a type that works then carry on, that's experience, otherwise use caution.

I suppose the only way is to suck it and see as we are also not privvy to Thorns original design criteria

see, I am a mine of useless information lol

I've had the set on for 15mins and the new flyback tuning cap is cold to the touch. I will leave it even longer but certainly I believe its more than up to the job.

The tuner has all but fallen apart and may not be helping three of the selectors are locked in and one seems to tune but I'm not happy with it. I might see if I have a spare tuner in stock, then again I might just put this to one side.
