Re: Go Figure... Tubes
If you're dealing with heat from an amp, a simple way to move it is to have vents in the ceiling above the amp or amps. A bit of dryer ductwork and a slow speed fan can send it outside. A customer of...

Re: Speaker /amp incompatibility
Hmm.
What's the possibility that this isn't the amp at all? What if the suspension on the woofers failed? Apparently they are not brand-new. I can't think of a reason an amp would start behaving... -

Re: Top brands that have no respect
Actually its because the digital release is likely to be played not only on a phone but also a car. There's no expectation of that for the LP release, so a good producer will see to it that the LP...

Re: Speaker /amp incompatibility
Normally I would agree- you make a change and things don't work right, maybe it has something to do with the change.
However, if the change introduced a speaker out of phase, while most of the... -

Re: Lifespan of Capacitors
No. I probably should have said 'any amplifier' but I surmised that this was in a solid state amp amp- and in a solid state amp there's no good reason for a cap to fail in such short order since they...

Re: Speaker /amp incompatibility
Your description of the bass is a dead ringer for a standing wave in the room.
The best way to fix that is with multiple subs. The Audiokinesis Swarm is intended specifically for this sort of... -

Re: Lifespan of Capacitors
Normally a cap of reasonable quality will go about 20 years even if there is heat (as long as there isn't too much heat).
If these parts were in a solid state amp I'd be concerned. Caps in solid... -

Re: What's surprised you gear or cable wise?
My Classic Audio Loudspeaker T-3s employ the TAD 1602 drivers. Fo of 21Hz. They are in a bass reflex cabinet. As you probably know, a bass reflex allows for bandwidth below the Fo. So the speakers...

Re: Attention all Luxman 595 owners - What volume percentage does it switch from class a to class ab?
The amp does not 'switch' between modes. It is more aptly described as a transition, one which you can't hear. Really. So don't worry about it. When you are pushing the amp hard to where is sounds...

I guess I've been in summer amp mode for several years, playing a set of class D amplifiers. I don't miss the tubes at all, and I'm used to playing triode power tubes.

Re: Amplifier Designed for KT150 Tubes
Right now KT150s have been very difficult to get!
I'd be curious to hear what you think of a decent set of KT88s in your amp. JJ makes a blue glass version that seems quite nice. -

Re: Question for the EE types about a SOLA Constant Voltage Transformer
The output isn't sinusoidal. Harmonics of the line frequency exist; the 5th in particular can be quite pesky, causing power transformers to run hotter (and noisier), rectifiers to become more noisy...

You won't be able to hear or measure the difference at the transition point unless there is a very obvious design flaw or malfunction. Think of it as a curve being grafted to a straight line- at...

The qualifier you added here is certainly true! But there's no reason it could not be done again. The EV amplifier isn't bad.
