I have considered the ClassicTone choke in the first place (since I've used their transformers before) but couldn't justify the shipping time & cost. Instead I went for a JCM800 choke made by Dagnall: https://modulusamplification.com/JCM800-Style-Choke-P5763905.aspx as i couldn't find exact specs f...

yup :) but it's in reference of page 2 or 3 where this particular resistor was discussed as a 680 Ohm. This mistake is logic as the red ring seems to fade/age to Brown like the one juste beside it, but beware ;)

R236 is a 6k8 Ohm not a 680 Ohm. I think the third ring as faded from red to brown on the resistor but it's pretty clear on the original LE/Blue Tolex schematics and a test confirms it...

yep on mine some retainer springs seem to have 50xsomething Hz resonant frequency such as the mains noise feels like double it is when blocking the springs

Looks like most of our 30th have almost the same stickers (is it the same in JCM900 from these years ?). WHO ARE : - Julie (PSU/Power amp/Preamp) - Josie (Power amp) - Alison B (control board) - Alison (midi board), not the same as Alison B, writing very different - MC (control) - MG (preamp) - AA (...

wow looks almost brand new ! I'm wondering if the choke would be a good addition. not much space to fit it on the 6101 chassis though. Which choke did you choose ? The classictone would be cheap and with the right specs but the shipping from the us is quite a steal… ($50 for a $21 part, not that it'...

About the 5.6k R between the green wire and pin 5, it really look like a typo BUT I'm pretty sure mine was factory mounted, this amp was never serviced before I bought it. It sure doesn't make sense but this mistake was still there on the tenth version off the schematic. Isn't there ANY way it would...
