Mexican radio on my VT-40....

[BobbyFudge]

I'm getting radio through my ampeg vt-40...with no guitar plugged in and volume down to 0?????

Why?

Thanks

Not sure, but now I have that bad '80's song in my head. Thanks a lot!

But seriously, my ampeg V4 used to pick up radio signals. Never figured out why.

You have the guitar 'tuned' wrong


The input jack may have the grounding lug sprung or dirty.If it isn't grounded it will pick up RF.

Too close to the border?

Press 1 for English?

Have a tech look at it. It's probably as simple as adding a "grid stopper" resistor to the offending stage that's picking up the radio. Unless you have a scope, and can find out what stage is picking it up, there's not much I can tell you in the way of mods to fix it.
Or it could possibly get fixed by something as simple as a little extra shielding in the cab.

Good Luck!

The schematic I was looking at is odd. Bright has a pass cap, then a 220K to ground. Normal has a 5M6 to ground.

220K, and 5M6? wow, that is odd. I'm not familiar with the amp, but from those input impedances, sounds like one input was geared more for a Mic input, (5M6), and the other.... Active pickups maybe? Unusuall setup for sure.

...you could also try just adding a ferrite bead around the lead to the grid.
