unless quite low powered, it is very unlikely that these SS amps actually disconnect the speaker and feed the amp's power output to the headphone jack. instead the jacking-in of cans probably redirects an intermediate amp signal away from driving the power (output) stage and over to the 'phones. speaker and power amp remain safely, blissfully and silently in union. however, some might interpret the speaker's silence as evidence of "disconnecting the speaker" and decide it's okay for any of various purposes to run the amp with a disconnected speaker/cab. so for a SS amp they came to a correct conclusion for the wrong reason. where the problems are: it is entirely possible to use a similar signal architecture (removing signal drive to input of power amp) for creating a 'safe' headphone out in a tube amp (power amp and speaker remain always connected). but there, drawing the that same erroneous conclusion that the speaker is being -- and could be -- safely disconnected in a user mod could lead to mucho nastivity.]]> Guitar Noise Lessons gnease https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/paged/2/#post-346979 https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/#post-346977 Fri, 29 Jan 2010 19:09:21 +0000 Guitar Noise Lessons gnease https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/#post-346977 https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/#post-346958 Fri, 29 Jan 2010 07:32:56 +0000 Guitar Noise Lessons Moonrider https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/#post-346958 https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/#post-346942 Thu, 28 Jan 2010 22:26:23 +0000
Where is Ric on this one? He probably fainted reading the first post and has not come to yet. :lol:

I just want to say the attention paid here to this is a statement to the quality of this site.

That's a very nice clear explanation--I like it. I see you updated the article already. The amps of the world all breathe a sigh of relief.]]> Guitar Noise Lessons EvilSpudBoy https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/#post-346930 https://guitarnoise.forum/guitar-noise-lessons/bad-advice-in-respecting-others-while-you-practice-article/#post-346913 Thu, 28 Jan 2010 17:33:41 +0000
Again, my apologies and I'll work harder (and hopefully smarter) in the future.

Please be aware that the advice in this article is meant, primarily, for those for have solid state amplifiers (the author himself has a Crate GLX 120).

With tube amplifiers, the situation changes. The speaker (generically, a "load") should not be disconnected from a tube amplifier without the substitution of a nearly equivalent -- but silent! -- resistive load. All the power that would have gone into the speaker ends up being absorbed in the power (output) amp transformer (part of tube amp design) and fries either the transformer or something else. It is entirely possible that someone HAS managed to do this with a tube amp and not damage it, as disconnecting a serial EFX loop as shown also removes signal from the power amp stage. That would save the tube amp. But even so, destruction is still possible if: EFX loop is a parallel loop (v. unusual) or the person forgets to reattach the speaker before playing through the amp normally.

Most solid state amps do not have this issue due to fundamental differences in principles of design and operational.
In other words, never operate a tube amplifier or any large wattage tube or solid-state amplifier without a proper output load: e.g., properly rated speaker, resistive load or power soak device. Only use this method on a smaller wattage, solid state amplifier.

And always consult the amplifier's user manual to confirm that no load (no speaker, no resistor, no power soak) operation will not damage the amplifier. Should this work and make everyone happy (and keep their amplifiers safe)?
