For your amusement
I found this bodge in an old tv I scrapped a few months ago. I don’t know if it was a poor field repair or an amateur bodge. It’s one of the worst I have seen. Norman

Re: For your amusement
That is pretty poor, I don’t recall seeing a job, even temporary, that bad.

Re: For your amusement
That looks like a genuine original BY100
Historic bodge! Couldn't even clean the glass and cement out of the octal base. David

Re: For your amusement
Looks like it ran for a while though, served it's purpose!

Re: For your amusement
Well at least it is easily reversible should a suitable valve come along.

Re: For your amusement
A real bodge wouldn't have the resistors.

Re: For your amusement
I guess it served its purpose - to eke out a few more months of life from a TV that really should have long since been lobbed into the local midden.

Re: For your amusement
Never seen anything that bad, just the usual dropper sections hanging like bunches of grapes from tired old dropper colums, are those parts even soldered?, horrible bit of work.

Re: For your amusement
The resistor has been shorted out!!! When I saw that and various other bodges in the set I decided to scrap it. There had been an attempt to solder the connections but that was poor. Norman

Re: For your amusement
would anyone think bad of me if I say I'm impressed? Field repair for sure. I remember being called out to an AEI mercury thyratron based speed controller at a textile mill in the late 80's to find the rectifier valve with an open filament. Wandering into the local B&O showroom (the only tv shop in the town) yielded nothing, so a similar bodge was effected. Vital production of the UK's velcro supply was ensured.

Re: For your amusement
I can understand a situation, perhaps just before a big sports event, when any thing temporary will do to get a set working, so in that respect it worked, however I still think it’s very shoddy.

Re: For your amusement
Is that not electric fire element wire wrapped around the resistors?

Re: For your amusement
Nichrome is a bu***r to solder!
OK confession time. I have been known to repair droppers by unwinding half a turn from each side of the break and twisting the ends together out of sight at the back of the dropper. Looked neater than a 10W resistor or RS "section" wired across. A manager I once had used to warn us against bridging droppers. He had a word for it, "kipps" "No kipps on droppers" he would say, does that sound familiar to anyone? He was a Scot if that helps.
