Re: Merry Christmas Amplifier Central Friends :-) Post Pic of your fav amp here! I left the charger to my camera in Texas so I don't have a working camera but here's a jpeg of the original art for the nameplate: You won't find one of these outside of my area...I only sold 3 of them.

Re: Merry Christmas Amplifier Central Friends :-) Post Pic of your fav amp here! Merry Christmas all! No surprises here!

Nice... Board cut in half and the preamp section replaced with this monstrosity. Another area repair shop sent this to me to sort out; they already removed the "extra" tube and tried to rewire it but it didn't work. It belongs to a backline rental company. I'll have to make a new board to...

One of my customers brought in a Soldano Avenger last week that had almost no output. He's only had it about 2 months; the amp is about 4 years old. I quickly figure out that it has a bad output transformer which was aggravated by an intermittent connection in the impedance selector. He asked me...

For those that are interested, here's a video of my amp in action. This is one of the bands a buddy of mine is in. He's playing the blue Strat and has a couple of lead breaks (at 3:48 and 4:41). This is an excellent example of how the thing cuts through in a live situation. I think he is using a...

Title says it all. Still having issues, particularly with FireFox...clips won't actuate. For those that never venture over to the sound off room, here's a link to my thread over there: https://forum.seymourduncan.com/showthread.php?t=206494 Edit: oh yeah...link to the site is in my sig.

Sorry about the rant here...but I gotta tell somebody! As many of you know, I am building my own amps now and am currently putting the finishing touches on my website before it goes live (by Jan 1). So, just to get all of the information I can out there about it's capabilities/limitations, I...

Re: GlassMan Tube Amps update! Ok...here we go...front view of the amp. The cane grille is beer bottle proof! And here's the promised 3/4 view..for proper perspective! By the way, it weighs around 40 lbs.

I pop in here on occation but have busy building amps; I thought I might give an update on what's going on for those that are interested... I battled an electrical interference issue in my shop that started mid-summer...in fact, I'm still battling it...the electric company is REALLY slow on...

This is intended for informational purposes only and is prompted by the third JCM 900 in my shop in a week for various reasons. Two of the owners ran them into a 4 ohm cab with the impedence switch set to (4)16. One of these guys is buying a new output transformer. The JCM 900 impedence switch...

I went to a house in the "hood" based on a tip from a friend that there was some old test equipment in the basement. The lady that lived there said that everything was from a previous tenent that had lived there for years. I found several old Heathkit devices (o'scope, capacitor tester, signal...

I am in the final stages of releasing my first offering in what will become my own line of amps and need to poll you guys for your opinions on this... The amp is a rather simple, single channel amp with reverb. It puts out 20 to 25 watts, depending on which rectifier is used (5Y3, 5U4, GZ34 or...

I just picked up an Epi LP std and was wondering what the stats are on the pickups. I am not unhappy with what is in there at this point; I honestly am still getting to know this guitar and haven't made any judgements yet. I simply am curious as to what is in there so, should I ever decide to...

So I get this early production Peavey 5150 in my shop for a low power complaint and to add a bias adjustment. I bench it and run it through its paces and determine that half of the power section is not contributing, so I measure the OPT with my multimeter...24% mismatch DC resistance...I assumed...

Like the ones that Fender used on thier point to point boards...but longer. Approximately 1/8" inside diameter and 1/4" long (for a 3/16" phenolic board). I'm deliberately staying away from turrets; I like the looks and utility of eyelets and my layouts and prototypes were made with eyelets. My...
