In general, a hifi speaker is not a good match for guitar. Hifi covers a full spectrum of sound, often 20Hz to 20KHz. (If you are over 40 years old, you probably don't hear very much above 12-15Khz and by the time you are 70, maybe 10KHz.) Look at frequency for the low E on bass and high E string on...

Less than prices listed by Mouser? Hmmm....

I finally looked at the layout. Frankly, a dozen pots on the front panel scares me. I'm pretty sure I'd need a 24" x 8" chassis to get all the parts in it. The cost of the chassis alone may be a discouraging factor. In a factory production situation, they know how to pack things tight that ordinary ...

It would help a great deal if you can tell us about your general background in electronics and whether you've every worked with tube amplifiers. Are you a college educated electrical engineer or maybe you've got some sort of technical certificate or military training? Built any pedals? Do you have t...

I'm a big fan of repurposing stuff like this. You received Telefunken 12AX7s and some RCA, too. If they still have life, these are a true find. (You said "Tesla" but I think you meant Telefunken.) I'd restore the Gibson if it's doable. As for the power supply, if it's something you want to have and ...

This has an excellent section on how to solder...for anyone who might need it. I found it very helpful when I started doing this stuff. Look around page 10.

Whoever did that should have his soldering iron confiscated!

Transformer bolt should not be used for mains ground. Drill a hole near where the mains enters the chassis, use a ring lug, bolt it down there. Nice looking amp...LOL! Good luck with it.

What are you really trying to do? The 5E3 is about 15W. The perceived difference in loudness between 10W and 15W is very small. To perceive a meaningful drop in power, I suggest you'd need to go below 5W and maybe as low as 2W. If you want 10W, just go for it. I'm just saying, before you go to the ...

The assumption that DCR is a reliable indicator is not right. Sure, it gives some information. At best, it's a hint. If you know the DCR and other wire specs, you might be able to reliably estimate the length of the coil. The problem with using that information to determine impedance is that impedan...

Auto-Align 2 eliminates comb-filtering, minimizes transient smearing, and spectrally optimizes the phase of each mic to deliver the full and defined sound captured by the microphones.

In other words, it sterilizes your recording and removes anything that might make it sound more natural.

You can make one of those. You'll need a phenolic strip and then some old terminal strips with the right stuff but wrong configuration. I don't think it's worth the effort. There is no shame in fixing it with what you can find. This is not the kind of repair that's likely to impair the value.

That's a really good looking guitar!

I do. You really can't beat it for price/value. If the offerings fit your needs, give it a try.
