Tube socket holes messed up???

[Adambomb]

I switched the preamp tubes in my DR about a month ago. When I got to the V5 socket (the last one) I thought it was a little hard to push in and it didn't fit all the way down.

I got some different preamp tubes today and started changing them....when I got to V5 I saw that a couple of holes of the socket were mashed and were kinda closed up. How can I fix this and can I do it myself?

If the amp were mine I'd take to an official Mesa tech to have the socket replaced, especially if the amp is under warranty. Usually the last preamp tube position is the phase inverter, very important to have that socket in undamaged condition. Doubt that the repair would be covered under warranty, though.

Now that there is at least one post here I'm sure others will follow. Some board members are amp techs and might have ideas to help you. Best of luck!

Did the same thing, fixed it by removing the amp from the box, took a small small jeweler's screwdriver and re-bent (official Red Neck word) the tabs inside the socket to hold the tube. Now, I know I will eventually have to take the amp to the doctor, but it's been working fine for 6 months now. Next time make sure all the pins on the tube are straight before crushing them into the amplifier. You can also try a little TV Tuner Cleaner from Radio Shack on the ends of the pins as lube, just give it an hour or so before turning on.

NOrmal warning...dangerous voltages are present. Using a conductive screwdriver to staighten out thos pin clamps can be dangerous. At least two of those pins..1&6....have amybe 200 volts on them. That metal screwdriver can take that voltage to ground quickly.
Adam, I agree with fish that the pin clamps can be resurrected...do it with care or take the amp to a tech.
there is a way to feel tubes into sockets. For me, it involves rotating the tube until you feel the pins fall into place. Then, try a gentle pressure to insert them. REsistance means you need to back out, survey the tube's pins for deflection, straighten them if necessary and try again.

My tube socket was far beyond fixing so I took it to my local tech and had him put a new one in for $25. Not a bad price at all.

I'd be real good friends with a tech like that! Quite a few charge more than that just to open up the amp and look at it!

Adambomb, if your tech charges everyone that way, he will not be in business for long...or maybe it is a sideline for him????
That is not a fair charge....good deal for you, though.

Well, I have been going to them for about 14 years too. Know the owner and his family.

Longterm business relationships work that way.
