Solderless Tube-Amp

As you know from our Mojo-Experts the type of solder can have a big influence of the sound. Many years ago Guild recognized this problem and to avoid any negative effect on the sound didn´t use any solder as you can see here:

How is it held together?

Mojo Juice, of course.

Can´t you see the block terminals (instead of solder) ?

A positive side-effect ofthis is that with this "tweak"-amplifier even want-to-be-boteekers without solder-skills can start their own business only by fumbling around .... with a screwdriver.

Now the tone-loss is generated in the contact points.
I trust in solder and a good layout (on Ted Weber's website is a nice example for this).

If only people knew how little thought is put into the layout of most of those designs. They are either a direct copy of an old Fender layout or a hodgepodge of whatever. The component layout for the circuit board of the Heather kit was done in about 15 minutes. I just grabbed the parts and stuffed 'em into the board however. I kept some rules in mind while doing it, but I displeased with the choice of board I was given to use (I was forced to use that board - I originally wanted to use one that was very different), so I just kind of did whatever - I figured that if it doesn't work, that's not my problem because I'd built three already using a different layout that works fine and Ted refused to use the board I had spec'd, so I figured it serves him right if it's impossible to build. That's the kind of "engineering" that goes on there.

Well, I've actually repaired a Silverface Twin, more than 20 years old, where I found a plate resistor and a coupling cap twisted around a 12AX7 socket pin, and still unsoldered. Needless to say, the problem was somewhere else. Of course I also soldered them, but they had been working flawlessly from the very beginning. Incredible!!!

About three years ago the Tele I'd built up back in '89 was acting up. Small intermittents when flinging it around and beating it on stage. Opened it up and found no solder on the volume pot conx. Pretty good run.
