The Amp Garage

I am converting my Marshall JCM800 4210 to 4010 (50w split channel in a 1 -12" combo to the single channel version) I have done a half a dozen tweaks and have never been satisfied with the sound of this amp. I am dumping the reverb and effect loop and dropping in a new turret board to make a straigh...

I just saw this one. Sad indeed. Golden Country and Flying Turkey Trot are two of my favorite REO tracks.

I did not see a cause of death. 65 seems pretty young to me these days.

When they got away from the cloth covered wire the lead dress suffered. Still a great amp though.

I finally found a chance to watch the first clip. The most amazing part to me is that Bonham is able to change shirts and change back without missing a beat! Oh, and that drumming thing he does was pretty good too.

On vinyl, it was Bachman Turner Overdrive's Four Wheel Drive album. I believe my first 8-track was Aerosmith's Toys in the Attic. I had one of those portable 8-track players that looked like a detonator box. The handle on top was to change tracks. I carried that thing everywhere as a young teen.

I would say that the 250 is built a little differently. Everything is in one chassis, but the construction looks similar. I would be surprized if they didn't share some circuit design.

Here is the schematic for a Sano 250 that I repaired a couple of years ago for a friend. It is an accordion amplifier. The tremolo is magical. Not very loud though.

I also have an associates in Electronics. It has been 27 years now. My classmates scattered in all directions as far as career paths. Being in Texas, there was a lot of opportunity in Oil and Gas and I have done pretty good for myself. I did have to work my way up through the business and it took qu...

I too was born in 1963. I have vague memories of the tube tester at the local hardware store. I started playing guitar when I was nine, but I was sixteen before I got my first electric guitar. I went through a couple of transister amps before I could afford a used tube amp. In Houston in the early t...

Mr. Fahey makes some good points. I use 3D modeling software at work. The learning curve is extremely steep, weeks of training, then a couple of months of struggling to become productive. Personally, when I find time to actally design something (tube amp related), I will use Visio. There is enough p...

vintage 12AX7 types can still be had at reasonable prices. Organ pulls can be cheaper than new production tubes on eBay and sometimes here. I ordered NOS Tunsgrams when I built my Express (because it was recommended in the build notes) and was happy from the begining. I fired it up initially with so...

I am slowly preparing for a rebuild. I am converting a 4210 to a 2204 combo. I owe a lot to the forum for the knowledge. I'll start a thread when I get under way. Basically I am starting with an empty chassis and the transformers, so it is mostly a build.

If you really want to re-use the eyelette boards, you might try treating them (carefully) with a heat gun. I have done it one a vintage Fender that I rebuilt with good results.

He is one of the few that Chet Atkins bestowed the CGP moniker on. His version of classical gas is amazing.

This is a shame. I am not the best player, but I get a lot of joy out of doing it. Sometimes you have to look backwards to go forward. Is there a time when you really found your bliss playing guitar? Your answer is there.
