The Amp Garage

And here's the same amp being used by another band----- the white, rectangular thing sitting on top of the 4x12, 2x12 stack of speaker cabs---- no pedals used just the amp turned up to "10"---- The tone sounds fuzzy and flabby to me but this band, and many others, seemed to like it---- This amp was ...

Here's a vid of one owner of a Bogen CHB35A Plexi rebuild I did long ago sitting in with a local band------ the white head sitting on a 2x12 cab, 2nd from left. This is the amp I bought back just to keep people from using it out in public because it is ugly and it doesn't reflect the work I do now. ...

What a mess !!! Amp build looks like some of the earliest Bogen PA head rebuilds I did------ mix of used and new components, sloppy wiring/soldering------ Everybody has to go through some sort of learning curve when building amps but being proud of work like this is a strange thing. I hope the amp d...

Amazing----- :shock: ----- I suppose it gives some people something to do------ But which ones to stock !!?? The "real" former Sozo's (now being sold under a different name) or the NEW Improved Super-Duper caps that are made by a completely different company with different manufacturing specs ? Whic...

I've found this Edcor to be an excellent PT for 2204 type builds that will benefit from a non-stock, higher capacity power supply----- it is rated for 250 mA vs the stock 150 mA---- B+ will be @420-425V. You can use the same rectifier and bias circuits as in the 2204 schematic. Save the 100 watt Mar...

Nice! V30's in the orange cab ? Love to hear your Kt88 if you get the chance. D That's a 70's Orange cab with two orig Square Magnet Eminence's and two much newer Emi GB12's------ the speakers are nothing special but that cab is the best sounding Orange 4x12 out of three in my shop right now. I'll ...

This one is five gain stages plus a CF driven tonestack------ I'm not sure if it is a direct copy of another amp or not. This one was built almost a year ago but no vids were done until the other day, I also built a similar 5 gain stage 50 with KT88 x 2------ I'm building a "Big 50" on my bench now-...

I built this 100 watt, EL34 x 4 hi gain head and my friend stopped by my shop to try out different amps---- he liked this one the best so I hooked up the vid recorder and caught him playing---- no delay, no post processing, running through the 70's Orange 4x12 can with two orig Square Magnet Eminenc...

Here's a vid by one of my amp customers, Eoin (said like Owen)---- he's playing bass (with many effects) thru a DR504 clone I built for him early this year--- the big black head with my MULE logo on the front. Interesting to see what some of my customers do with the amps I make for them----- This is...

That's the power resistor that the 5150's use instead of a choke----- that one looks heat damaged. Just wait until it's time to change screen grid resistors on that amp---- you have to drill out the rivets holding the power tube sockets in place (to remove the power PCB)----- replace the bad screen ...

Wow !!! Arc City !!!

gldtp99 Thanks for the info hope you document a build if you decide to build another clone rotary switch for FAC is MBB or BBM make before break or break before make, or does it matter? https://www.tubesandmore.com/products/P-H392 https://www.tubesandmore.com/products/P-H393 also wondering if the s...

I just built another DR504 clone for a local bass player----- I used a mix of Mojo Dijon and M150's----- the 47n Mojo Dijon caps are very large in diameter so I used M150's in the 47n and 100n board positions for a neater fit. I still had enough yellow M150's to do the job. FWIW----- George M. (Metr...

Thanks--- I took my 1974 Orange OR80 to my shop today for a check over and to fire it up---- it had been sitting in storage for a while. I installed the stock 330pF bright cap on the Vol pot----- I didn't put a bright cap in this one when I replaced the Vol pot as part of the initial service, yrs ag...

Vid of a 74-ish OR80 clone I built several yrs ago----- the player who bought it did this vid a couple of weeks ago.
Amp is sitting on top of the Mesa 4x12.
I used a Twin Reverb replacement PT and an Edcor 100 watt, 4.2k primary OT, Mercury 10H choke.
