Lonestar Specil no sound

[dc3c46]

Good day Guys!
Perhaps one of you can direct me to the root of my problem:
Lonestar Special played today with no problems for about 2 hrs.
Turned off.
On again after 1 hr.
No sound. Fuse good.
Nothing came on in all settings (5w,15w,30w)
???
Cheers,
C.J.

Does it turn on? Lights on, no one's home?

I just googled it and it's a Boogie tube amp, so always remember there a DEADLY voltages present inside. If you haven't got the tools and/or don't know how to use them, or have no experience working on tube amps, take it to a professional. Ain't no shame in stayin' alive!

One more thing.
(if it lights up/turns on)
Plug a short cord into the send & return jacks on the back and see if you don't get sound.

Next, if still no sound, pull the speaker cable and put a fresh 9v battery across the plug tip and shield. If you hear a pop, the speaker is good, if not, something went wrong with it.

Thanks for the reply!
No, no light turns on, spkr is fine, just ran my Fender blues Jr. in the cabinet and sounds ok.
Could a resistor been blown?

Open it up and look for parts that broke off the circuit board, especially big sand block resistors.
Look for burned circuit tracks where the big resistors are soldered to the board.

You probably would have heard it, smelled it, or both.

Are any of the tubes lighting up? If not, then there's an AC problem, like an open fuse, open power switch, loose or open AC cord.

It's a big resistor, to drop the power supply voltage.
Nothing is holding it, except the leads.
The amp is transported and it breaks loose.
No, you do not hear it or smell it.
The resistor breaks and the amp stops working.
That is all.

Oh I like that troubleshooting method.
