Hi everyone,
A friend of mine has contacted me (because i dabble with Scopes from time to time) about his Tek 453, its been sat in his garage for a while and is in bit of a sorry looking state but he wants to use it for some repairs on his Motorbikes. Ive only seen a photo of it so far, and he says that the fault is that the scope will Trigger on Channel B but not Channel A.
He hasnt double checked it yet, but he does believe it has a 6x10cm display, so we think it might be a pre 1971 model (his photo also shows 453 not a 453A), which if TekWiki is correct, means its more likely to have Nuvistors inside.
As im not familiar with the Tek scopes of this vintage or Nuvistors for that matter, im wondering if its really repairable or not, it will be a few weeks until im over his way again to get an actual look over the instrument. Just looking for some thoughts/opinions on the practicality of repairing these. Admittedly from browsing auction sites etc, it doesnt look like the 453's are all that common in the UK. Not yet browsed any service/schematics yet so may not even have any Nuvistors in the trigger circuit etc, but want to feel a bit more confident about it before agreeing to take a look at it for him.
thanks in advance,
Taylor
