Hi all! New here, hoping to get some advice. I purchased this Trinity tweed second hand through the Canadian Guitar Forum - it is the very one used in the demo
video on the Trinity site (though it now has a different speaker). I'm not well versed in amp technology, which is why I bought a complete amp instead of a kit. Now, onto my issue. When I crank the amp, after playing then muting the guitar, the power
tubes continue to "pulsate" back and forth, with very noticeable sound coming from the amp - almost like a tremolo effect. You can see the
tubes glowing back and forth. Here's a
video I just posted to YouTube, but note the sound is much louder than what appears in the
video. You can even see the
glow of the
tubes bouncing back and forth (hence the dark
video). Can someone explain what is going on here, and any ideas as to what may correct it?
Thanks in advance!
