The Amp Garage

I'm getting a sinking feeling, like I'm up the creek without a paddle. I think you may have the wrong paddle. There are voltages on the schematic. Have you checked any or all of them? That is where I would start. Tell us what you find. Let's verify that that the power supply is working properly. BT...

Thanks John.

The resistor in question is the 100 ohm resistor following the 2N6556 transistor on the the lower right-hand corner of the I-490 Board (Power). See Attatched Schematic.

I'm total transistor noob (knob? LOL). How do I check them... I don't have a data chart, unfortunately.

Basically, this is my issue: In the attempt to reuse a Traynor TS-50 (solid state) Chassis and Cabinet for a Stangray Clone build, I rehoused it in a 1U rack unit... Now, when I turn it on, I get no sound and it keeps burning up a 100ohm resistor (well, at least what I 'believe' to be a 100 ohm resi...

Planning a few F1 Builds. Just wondering if a 5Y4G rectifier tube and a 6K6 would get me there...? 12ax7b for V1. I have no experience with either tubes and was wondering if they will do. I've got 6 of each... Marconi Radiotron (made in Canada) 5Y4G/6F6 G and 6K6 GT/6. Afew Philco, too. They're not ...

The "Country" bank has some nice patches that help nail those elusive Queen and Boston-esque type harmony lead sounds. The trick is to use the unit in parallel.

Apart from my ol' faithful Eventide H3000s, the only other piece of "old-school rack gear" that I refuse to part with is a little-known (perhaps, 'long-forgotten'?) Pitch-Shifter/Chorus/Harmonizer: Digitech HM-4 Harmony Machine. Any love for the HM-4? The HM-4 is an integral part of my so-called 'cl...

The 20w sounded nice. However, it's hard to go wrong with a tried, tested and re-refined platform... props to the kid playing in the demo, good chops! I thought that the 50w sounded a little sterile and stiff... perhaps, due to the limitations of the demonstrator? These amps are aesthetically pleasi...

That was refreshing. Interesting design concepts.

I appreciate your indulgence.

"Focused" or "Flabby"?

Is there any advantage, one way or the other, to putting jumper wire on the top or bottom of the board?

I like the "Matchless-styled" mismatching speakers...

Is this RJ's layout? Just curious. I'm gonna build one of these someday!

Where did you hear about this? Very interesting.

This product will sell very well, most certainly. I am sure that many novice builders will take this on as a first-time project... and, thus begins the journey!

Jon Lord was perhaps one of the greatest rock keyboardists, ever.

One of my favourite bands, btw.

I've got a few old pick-ups lying around. They were mostly swapped-out from various guitars that I've owned over the years, when upgrading to something "better". I was just wondering if there is any use for an old guitar pick-up, other than a "Guitar Pick-up"? Hum cancelling in a spring reverb? ...L...
