Yes, using either a multimeter or capacitance meter, for resistors, diodes and capacitors, not so easy with IC's though. To do that you have to take it out of the circuit, by de-soldering one end of it. don't go there. The IC maybe, I wouldn't worry as much about caps, resistors, diodes. Don't...

As far as the "what have I done", what he did was mistakenly turn off the beacon light, which would be an action. Aside from that, though, we sometimes refer to omissions (something not done) as actions, although I guess it is technically incorrect. One example - to forget a woman's birthday...

A 2 sided pc board will have traces on both sides, although not necessarily any solder pads on the top side, since usually everything is top mounted and soldered underneath. Generally, simple circuits are 1 sided, more complex circuits are 2 sided. I spent several years as an electronic tech...

That happens sometimes to those of us who are very experienced at desoldering. I use a Soldapult (sp?), which is a device that sucks the solder out. The solder braid, IMO is not very good for a job like this. Sometimes you need to use a little piece of wire to rebuild a missing trace. You may...

When you look at it on an oscilliscope, the DC from a rectifier of a power supply looks like a dotted line; a short duration of current, followed by a short duration of no current. What a filter cap does is supply current to fill in the gaps. It charges up during the period of current, and then...

All the little single ended 5 watt, low priced amps that I have tried and owned, with 1 exception, all sound pretty bad, and apparently suffer from the exact same problem - The output transformer they put in them is way too small and has excessive core saturation. It "chokes" the output from the...

All the little single ended 5 watt, low priced amps that I have tried and owned, with 1 exception, all sound pretty bad, and apparently suffer from the exact same problem - The output transformer they put in them is way too small and has excessive core saturation. It "chokes" the output from the...

The first thing I would check is to make sure the ground wire to the bridge is connected properly. If it is not, you will get the symptom that you describe. Touching the strings should not make much difference in noise level if the strings are properly grounded. I just recently had that same...

I can't stand chorus, never use it. Ever. I lived thru the 80's - heard enough of it in that era to last the rest of my life. I do think it works better as an effect for recording rather than live use, at least in the type of venues / context that most anyone in this forum would be playing.

I'm guessing (pretty sure) that no matter how you program it, the signal at the outputs have been processed; any type of processing is going to degrade the signal somewhat, no matter how good the quality of electronics. You would have to look at a block diagram of its innards to see if the...

Definitely try the other RCA cable set. And a new tube in the reverb driver position. If you don't have an extra 12AT7 to swap out to test that, you can use a 12AX7 temporarily to see if that restores functionality - it won't sound right, but if you hear reverb, that was it. The last time I...

In that pic - do you see that black ring in between the shield and the inner conductor? That apparently is the black stuff I referred to earlier - that must be actually part of the shield, and is a conductor; it must be the "carbon" part of the "The proprietary double Carbon/Braid Copper shield...

Rosin core means it has flux inside, it does not designate the alloy. Electrical solder has traditionally been a lead/tin (easy to solder and get good connections), but some is a silver alloy - the container should indicate which type it is. If it is silver, I would bail out on that and get some...

You aren't using silver solder are you? I have heard that stuff is difficult to get a good joint. I guess it takes a hotter iron or ?

Does the cable you are using have a black layer of film on the inner conductor? If so, I have read that a particular type of cable has that, and if that film touches the tip connection (it is in contact with the shielding throughout the cable), it acts as a "semi" conductor, like maybe 20, 50...

No, zero resistance is a dead short, zero ohms, just like a piece of metal - shorting the OT's one secondary lead to the other. No load at all would be infinite resistance, the OT's secondary leads are not connected at all. No load (infinite resistance) on a tube amp when it is operating can...

+1 Some tube amps are wired that way, (for all I know, maybe most of them...) I guess the thinking is that if the end user unplugs the main speaker, that shorting the speaker output to ground is the lesser of 2 evils; the only other choice would be no load at all. Fender Hot Rod series are also...

It is hard to tell from pictures, but the bridge pickup looks very high to me - are you depressing the strings in those pics? If not, it looks to me like when you fret that the strings might actually touch the polepiece screw, or possibly the pickup cover. Depress the strings and see if the...

You obviously have heard me play....:D

Yes, what is "correct" phase anyway? Each preamp tube stage reverses phase, so a 3 stage preamp is reversed, a 2 or 4 is not. Reverb channels on BF Fenders, older Marshalls, '59 Bassmans... just 3 examples of amps that reversed the phase of the signal coming out of the guitar. No wonder they...
