good gas tight join
And exactly this was the problem for this amplifier, corrosion.
To be fair, I've got a Peavey KB 300 in the storeroom, sometimes it
needs a hit, when in use and I had several tube televisions and tube
monitors were I needed to re-solder, when they were old, not all
successfully. I still have got one monitor that's still broken after I
re-soldered it and a friend with better equipment re-soldered it too. I
know somebody having a very good discrete circuit Yamaha amplifier with
bad soldering joints. So from my experiences it's common that soldering
joints fail for television sets, but usually not for other devices,
excepted of devices that were soldered on Monday morning in the USA or
by soldering slaves in China.
Are you sure you cannot get leaded solder?
I did not search for it very much, until now I still have got half of a
1000g 0,75mm STANNOL S-Sn 60 Pb38 Cu2 coil, my favourite solder and
perhaps one or another mini coil of other leaded solder.
Lead free solder today might be better, than it was years ago, I didn't
tested it.
What was this thread about ;)? Chrome OS vs wire-wrapping :D.
