Hello to all. This is my first inquiry as to asking where can I buy potentiometers used by ENGL on their amplifiers. If someone can assist me with this requested data I will be very grateful. Thank you, David Hopkins

This is on a 1979 100 watt 2203. 4 stages of gain, non cathode follower. I inserted a 12VAC transformer & populated a DC Heater PCB I designed in Altium. I had 5 Metro loops in stock so I just popped one in instead of populating & using one of my own designed LND150 buffered loops. Thanks for...

I wanted to take this opportunity to thank Neddi Stanz for his incredible video & masterful playing demonstrating my Divergent modification on his 1974 Marshall Super Lead. David Hopkins

Demo of a new circuit in progress. All comments are welcome. The “Divergent” allows the guitar to plug straight in to the amp as with all of my work. I may install a low mid switch but I am going for a really rich saturated Marshall tone I hear in my head. Right on the verge of inarticulate...

This preamp has sold but thought I would have some fun and add a video to the search menu due to so little data available. I laid down a couple Cantrell riff’s using a JMP 2203 Power Amp section with a Vintage 30 Marshall 412. Same circuit many are building related to the Snorkler, Bogner...

It has been about 18 months since I had Carpal Tunnel surgery on my right hand. It is just starting to synchronize with my left hand. I have far to go but am making progress. The best way to explain it is to say my right hand feels like the steering wheel when the tie rod has fallen off.?

Hello. As the tittle suggests, I am interested in learning the lineage of Dave’s work modding high gain Marshall’s. That is to say did Dave call the amp we now know basically as the BE/HBE Marsha first and if so what year to year. Then perhaps dropped using Marsha and rebranded the Kitchen Sink...

Hello to all and thank you for checking in. I have made a couple changes to my Pandora circuit that really accents the growl without loosing articulation. This is built on a post 1984 JCM 800 Series 1987 Model. I am not a fan of these PCB’s so when modding to high gain on this platform much of...
