I'm not expert, but I would space out the connectors a bit by slightly bending them. That should solve the problem.
Thanks for the response.I'm not expert, but I would space out the connectors a bit by slightly bending them. That should solve the problem.
Not a good idea for power tubes (or ANY tube, but the mini's are less susceptible). The reason: seal stress. A tube's seal at the pins are designed so the metal and glass expand at the exact same rate. This is achieved when the whole unit warms up, as in normal operation. By applying solder heat to one point, you've made a point-of-expansion and until the joint cools to the same temp as the rest of the tube, air molecules are seeping in.You could tin the tube leads with solder to make them a little bit bigger, hence tighter.
Not meaning to be silly but if you haven't done this before please note that bending the pins is a tip only for the smaller miniature tubes. If you try it with the 6L6 output tubes they will probably break!I have 2 old Fender tube amps and some of the tubes seem somewhat loose in their sockets.
I would prefer not to change the sockets, which I assume (possibly incorrectly) would be the logical approach to solve this problem.
Any other solutions to this problem that have lasted the test of time?
Thanks Wild Bill...no buzz/noise from the springs? (see post #3)I've put these in a number of old Fenders and they work just fine!
I've never had any buzzing or noise coming from the spring tube retainers. The other option is to try and tighten your pin slots in the socket themselves. You can actually buy a tool for doing it, but I use a jewellers screwdriver and gently slide it down beside the pin slot and push it tighter together. It works good and tightens up the hold on the tube itself.Thanks Wild Bill...no buzz/noise from the springs? (see post #3)
with the amp's power supply caps discharged, you can pull the tubes and re-tension the socket pins. A small pointed awl or equivalent tool is used to reduce the diameter, hence improving the gripping surface, of the pins.
Of course, but by rattle, I meant when you touch the tubes. It would think it's safer to have the retainer properly fitted than not.This is how it is done and is usual but BE SURE the caps are discharged. Use a meter.
The tubes pins should be as straight and perpendicular as possible and there is a special socket for repairing ones whose spacing is out of whack.
You might keep a new regular socket around just for this purpose since those special ones are hard to find.
The reason being that it can make them hard to put in, it causes the spacing to be off, which is why the socket became loose in the first place.
You can also do it by eye (9 pin mini's only)but dont bend the tubes pins too much they break very easily.
If the octal tubes pins are bent. Dont chance it, leave them, they are hollow.
PS If you can hear the retainersprings rattling in there your not playing the amp correctly...TURN IT UP!... )
Where do you get the Belton sockets from?I use Belton tube sockets with tremendous success.
