If the tube is wearing, the cathode-to-heater current may leak too much

and that may sag a supply line. The relay would not fully energize, it could dither.

Thanks a lot

It can be three things,...

 

-The power tubes (valves)haven't been replaced and re-biased in 18-20 months. If

they are getting old and failing, then they may be pulling down other circuits.

 

-Or if the tubes (valves) are not the specified tubes (valves) for the product, the bias and heater

voltages might not be correct for other tubes.

 

-Could be the foot-switch circuit in the back of the amp.

 

Both would have to be looked at by a Line 6 authorized service with access to service

info and Line 6 technicians for that and other products. Tube (valve) amps have high voltage

lines which are shock hazards in them, and should be serviced by an authorized technician

who knows that product.

So you're saying that it's probably the tubes that are causing problems in the channel switching?

Yes the tubes have more than one year...

Hello, I started this topic is this section because you don't have a section for my amp.

I know my amp is a bogner but they told me that it was manufactured by line6 so I'm seeking help with you.

When I connect my footswitch, sometimes the amp randomly changes channel.

I have a friend that also has that amp and his started to randomly switching channels even with the footswitch connected.

I believe this is a problem with the relay switching, maybe it gets overheated os something...

Can you provide some kind of help?

Thanks
