Jon, Just wanted to say I've found you to be very informative and though I understand your frustrations I hope you stick around. You have a ton of knowledge and many of us can and want to learn from the likes of you and your level of experience!!
I was reading in a different forum that a Marshall JCM800 2205 amp was modded in the following way.A cap of 1uf was added in parallel with the r24 or r25 1.5k resistor,dont remember,on v4 which is the first gain stage after the effects loop.Now I am pretty sure the preamp layout is the same in a 2210,which I have.Now what exactly would this do,sound wise?The guy said his amp screamed afterwards.Is this a good thing to do since it seems like a pretty easy mod? Thinking about doing it.Thanks again.
I just find a post about power transformer for a Marshall 1959Hw and
you seems to have a solution for better prices ( less than $265.00)
Is it possible to you to send me the link ( you have PM to the other guys)
Please sent it to me at : firstname.lastname@example.org
Hello, I was wondering if you could take a minute to look at a thread I just posted in speakers and cabs called 8 ohm speaker wiring? I don't understand if it matters which way I wire my cab.
I don't know how far your contacts spread but I am having issues with one of my amps and might need to take it to a tech. I usually can fix most of my issues myself but I am having problems with my JCM 800 and was curious if you know a good tech out on the east coast (I live near Boston). I don't trust a lot of people with my gear and would like to get someone that will not BS me. I know you build amps but I am not sure if you do repairs. Also shipping to Fresno would be quite pricey. I posted a clip on youtube of my problem but have not got any responses, here is the link:
Jon, you're one the smartest guys on here. What is your opinion of the THD Hotplate? I have a shot at one for a pretty decent price and am thinking about going down there today and grabbing it. Thanks for any and all input.
Forgot to ask. Looking at the assembly instructions it turns out that the bias is fixed, as I understand it it means that I have to change a resistor until I find one that gives the right value when I change tubes. Is it possible to instal an adjustable bias pot and how is it done?
