Bugera G5 head stopped outputting sound

[ehdwuld]

So inleft my G5 on for a few hours the other week whilenibran errands

When i got back it only crackled on the output

I check the effects loop and it sends signal

The DI has signal

Seems to be the power stage

Tube glows

With the price of replacement tubes now, i wanna be sure that's what it is before spending that much money on an amp i only paid $250 for new

Granted the price went to $450 before Christmas
to $350 last week.

Take the tubes to your local old-school TV repair shop, they will most likely test the tubes for free.

You haven't been to rural America lately have you

The tv repair place became a video store in the late 80s
a karate school i the early 00s
And got bulldozed about 10 years ago

Thanks

I should invest in one of the tube testing machines online

My Egnater Rebel did exactly the same thing couple years back. After taking it apart it turned out to be a burnt resistor in the effects loop input stage.

I thought there was an LED that lit up telling you if the tube was bad?

Aside from that, DI outputs are usually tied to the output, meaning if it works, your tubes are still working. Generally anyway.

Have you ensured that it is not the speaker and or cable that has gone bad?

Based on what you're saying, you have an air gap between the output tubes and the speaker.

Yeah the tube monitor looks good

The di ihas signal present

And speaker was the first thing i checked
This amp feed my mini stack of 1x12 and 1x15 cabs

And yes reading those from the cable reads the 8 ohms expected

I will stick the tuner in the loop to be sure i am getting signal out the loop

I have tried jumping the send / return on the loop like all my other amps needed

That doesnt cover it either

It may be the specker out jack or resister as suggested earlier



As for the country of origin posts
most manufacturers have a Chinese made product
that not indicative of any solution
Thanks for stating the obvious

Agreed that you can't solely judge a product based on it's county of origin. My Egnater rebel 30 is made in China and it's the best amp I have.

There is an old school TV repair place by me still kicking, I figure it's a drug front or mob social club in reality

Seems like it's usually an 80 year old guy that doesn't want to retire because he doesn't have any hobbies

Yeah, totally possible

There are so few user serviceable parts in a TV now -essentially the transformer or a few daughter boards or a molex connection/ribbon cable are about it.

If they are still around, I suspect they are spending their time on other appliances these days

so I tried swapping tubes and this amp only has a single preamp AX7 and a single power tube 12BH7 (mojotone had some Yugoslavian ones for $10)

that didnt help at all

so I pulled the pan out and there was, as predicted, a resistor with obvious heat issue that was open

I will post an image shortly

I asked my EE and he says he thinks its a 100 ohm resistor black brown

it looks black blue to me

I asked Music Tribe they sent me a broken link to a parts vendor

exactly no help but it was timely, they answered in a day
