| Cursitor Doom <curd@notformail.com>: Oct 07 04:08PM Hi all, I just fixed up this classic Tek 466 scope I've been meaning to get around to sorting out for the last few years. As you can see, my soldering is atrocious. I've been soldering this type of circuitry for 50 years and never got any better at it in all that time. When it comes to soldering and part-placement, I suck donkey dick! Check it out and enjoy at my expense: https://www.flickr.com/photos/128859641@N02/45109856712/in/dateposted- public/ and... https://www.flickr.com/photos/128859641@N02/44247281105/in/dateposted- public/ As you can see, the "world's worst" tag was no exaggeration! -- This message may be freely reproduced without limit or charge only via the Usenet protocol.

If there's black muck involved, clean the joint better. NT |

You got some very good advice already. Just want to point out that failed output (end) transistors nearly ALWAYS short out and blow fuses. I've replaced thousands over the years. I also want to point out that soldering as an electrician is probably different from soldering in a receiver. I recommend getting an old piece of electronics to try replacing a component and see if you can do it reliably. Better to find out on a piece of junk. Older circuit boards have a higher failure rate due to excessive heat. I had an old Sony board where the pads lifted too easily with a 700° tip but were OK with a 600° tip (Metcal). I like old HK gear and would prefer to hear you have it working again. G² |
