Re: Trek II - UC-1A Universal Combo Preamp

Great contribution, thanks so much and welcome to the forum! The unit that I traced has been modded with two extra outputs on Speakon-8 connectors and a custom speed control unit. Two resistors are removed to defeat the +33V phantom voltage for speed control on the balanced signal output. Not sure ...

Re: E.M. Lyndsell, Automatic Phase Box, Everyday Electronics December 1977 🇬🇧

how to add depth or feedback mode for this circuit? Start by building it as-is, and hope for not too many errors in the schematic. Layout has been made, but not verified, I suppose. These old magazine schematic are prone to contain mistakes. Many other verified phasers are available on the forum ...

anyone has the correct schematic?
There is one in the beginning of the thread. Please don't use crappy blog sites like tagboardfx. No schematic, only layout: do not build! How are you going to debug with a layout?

Re: Old Donner Ultimate Comp Repair

First step: open it up and have a look at what is really going with the DC jack. If somebody would come on here and tell you what's wrong with the pedal you didn't even open up, would you believe him? You might have to replace the DC jack - but if you don't have soldering gear, it's better just to ...

Re: Germanium in my attic

How to score germanium for cheap: 1. Search local, non specialist, second hand sites for pre 1965 electronics, preferably without brand or model number (they are cheap) 2. Use the picture on Google Lens (image search) and find the brand and model number 3. Put the brand and model into http ...

Re: WEM, Watkins, Rush - Pepbox, Rush Pep Box [schematic]

I just had a chance to play one of the versions built by Lucy for Macaris. JHS demo is really accurate-sputtery, poor sustain, harsh... Cleans up really well, surprisingly, to a clanky/treble clean. If you're into noise-making this is perfect. For controllable, classic sounds, not so much! Are you ...
