Starting to put together parts for a 5E9-A Tweed Tremolux build.

Look better? Sound better? Higher resale? I built this 1x12” extention cab from an old cherry board and stuck a UK made Vin30 inside. 50 years after all those Monoprice amps are in a landfill this will still be kicking a**. Build your own cab and stick a 12” inside. Never know when you’ll want...

Nice work, but you’ve started out with a lot of mods already applied. Now you’re pedaling backwards trying to get your tone. I’d at least start by replacing the coupling caps with the original values. .02 and .05 in place of 0.1uF is gonna make it brighter. And unless tighter and brighter is...

As soon as “reality TV” was born variety shows died. Sex sells, and there’s nothing sexy about family oriented TV. Except for Sarah Purcell.

Sacramento driving has become hellish. Worse than Los Angeles. Why? Who knows. Lots of idiots out there. If I get brake checked I move into the slow lane and let them move on. I’ve never brake checked anyone. At freeway speeds that equates to road rage and can go really bad really fast. If...

John was the guy with all the songs in his head. He was a control freak, but finally agreed to let the other two guys write and record their songs and the trainwreck Mardi Gras was the result.

I just logged in so the site seems to be working.

Yea, back when I used a two-tube circuit to add reverb. Since gone to the single tube circuit.

The cherry cabinet is actually for my 1971 Vibro Champ. It’s a little taller than the original cabinet and fits a 10” speaker.

Tube Audio Supply sells these (through eBay), made by Heyboer…same as the Mojotone tranny.

Mojotone should swap this one for the 5F1 tranny. Same price and the primary impedence is close enough I doubt you’d ever notice the difference. Gives you both 4 and 8 ohm taps.

You can never go wrong with a UK made Vin30. In Fenders my first choice is always a vintage Jensen. My 2x12” test cabinet is loaded with a Weber Blue Dog and a Silver Bell. The two together are magic. For tweeds I usually lean toward a Weber alnico. 8 rib pulp cone to tame a flubby amp and a...

Thought about it overnight. Now thinking the big orange 25 watt resistor is being used as a ballast resistor, a conditioner to filter out wall voltage spikes. Anyone see this before?

Here is a BF Champ I re-capped a few months ago.

Twisted parallel filament leads help bring down the noise floor. That 222 ohm resistor is actually a 2.2K grid stopper, maybe installed to reduce some unwanted distortion. Looks like the NFB has also been changed from 2.7K to 3.3K. That big 25 watt resistor might be there to drag down the wall...

It can be green if you really want it to be. A buddy sprayed his red/black and it came out great.

I think the alnico was made by Crescent. No idea on the other,

The top pic is a stock Champ and below it is one that has a newer replacement transformer and the filament circuit has been changed to a twisted pair arrangement. Necessary? Some would argue no. Leo did it that way for a long time and a Champ is a pretty quiet amp, so might be time and money...

The original transformer (see schematic) had a B+ of 320vac. 275vac puts you in 6G2 territory. So yes, use the 325vac winding.

You want to use the 325v winding for the B+. Don’t solder both filament leads (green wire) to the same lug on the pilot light (as you’ve drawn). The original transformer didn’t have a 6.3 volt winding center tap, and used the chassis as the filament return. Only one green wire is connected to...

Maybe…

Good name for a scat band.
