Maybe you should try to get a solder with a silver/copper compund.

Or if you're feeling lucky, this.

Careful. It melts at 290 celsius.

60/40 works OK, but you would probably do better using a eutectic solder. Eutectic solders will harden much faster than 60/40 (they spend less time in that pasty transition period while cooling), so there is less chance of something moving and causing a bad solder joint. Something like Kester 63/37 or the one with a touch of silver (62/36/2 IIRC) are good, as is the Cardas Quad Eutectic, though that starts getting expensive. Radioshack sells some 63/37 and 62/36/2 in small quantities if you want to try stuff out.

The Mundorf solder is really hard to reflow, pack lots of flux if you want to try to work with it. I like Cardas Quad Eutectic and you get get it in reasonable quantities for cheap on ebay, no need to buy a lifetime supply. It melts pretty easily and has a good strong bond. The Mundorf solder's flux core smells tasty though.

I've tried a few others, but much prefer regular Kester 60/40. Radio Shack 60/40 is pretty good, too.

I don't get hung up on the metallurgy of my solder, which probably has little to zero impact on sound. What I think is most important is that it be easily worked and make solid physical connections. Having worked on plenty of old radios, bad joints in repairs seems to be a common source of failure. I haven't used another type of solder that flows and sticks as well as 60/40, so that's what I stay with.

Yet another RadioShack recommendation from me...

They have a Silver-Bearing solder spool that is .015" diameter, 62%-tin, 36%-lead, 2%-silver, rosin flux, and available locally. I use it for everything from SMD to cables. I only use regular 60/40 for heat sinks and tube sockets(large stuff).

Kester 63/37 for me. Also the RadioShack 63/37, but I wish it was a bit thinner diameter.

I think that is one the one that I used and didn't like it as it needed a lot of heat to reflow.

I'm using a 63/37 - AIM. I like that does harden quickly.

Thin diameter solders are very handy, I'm using a 0.7mm at the moment and it's great. Liquifies faster, and less excess.
