Question for Atmasphere re: class A output calc
Atmasphere,We are talking solid state. 0.1556A is the total current between two output devices (bias of 42mV with emitter resistance of 0.27ohm).Glen 
Can you get good sound bridging 2 Classe CA-200s
*You can get a technician to check the bias for you. Its not difficult to do but if you're not careful, a slip of a test probe can cause expensive damage. If you need the service manual, send me a PM and I will reply with a copy.*IMO, the AC suppl... 
Can you get good sound bridging 2 Classe CA-200s
Since I service my own amps, I've had quite a bit of back and forth with Classé tech support. I am reminded in an old e-mail message from them I have archived, that "in response to reports by some owners that amps were running too hot", they lower... 
Can you get good sound bridging 2 Classe CA-200s
As stated above, for many years I have been running Classé with speakers that drop below 3 ohms, also have quite severe phase angle, and never had a failure. 
Can you get good sound bridging 2 Classe CA-200s
I agree with the above. It is probably a good idea to get the amp checked out. It should not be blowing mosfet fuses repeatedly like that. Is the amp adequately ventilated ? Is your CA-200 a rear or side heatsink version ? I have a CA-300 (biased ... 
Running a dedicated A/C circuit
Type MC cable is an alternative to BX cable (a.k.a. type AC cable) but has not necessarily "replaced" it. BX cable is still actively used in some areas. Also, some jurisdictions do not permit plastic boxes or non-metallic cable. In such locations,... 
Plugging Amp into Power Conditioner???
For the past 6 years I have used my own tweaked out DIY balanced power conditioners, plugged into a dedicated 20A line. My latest implementation employs separate balanced isolation transformers for amp, preamp, and digital source. My experience ha... 
Modding Citation Amps
I know of an excellent tech who does restoration work on Citations and SAE. Send me a PM and I will give you his contact information. 
Audible Buzz from Lexicon: dimmers & microwave?
Internetmin, I have a DC blocker I built for a guy who backed out of the deal, all packed and ready to go. I've built a few as a favor to several Audiogon members. Send me a PM if interested."Testimonial": http://forum.audiogon.com/cgi-bin/fr.pl?a... 
how to check hafler dh-500
Agree on the possibility of DC at the amp outputs. If you have a digital multimeter, you can check the amp for DC. Make sure you have nothing connected to the amp's inputs and outputs. Set the DMM to the VDC scale initially, and connect the probes... 
Classe M1000
No problems with this amp. Send me a PM to obtain a PDF of the amp color brochure with technical description and full specs from back in the day.

Classe CA-101 Remote turn on Module?
Classé sells a remote pigtail with RJ-12 phone jack on one end and a small circuit board on the other end. You plug the pigtail into the remote jack on the back of the amp, and you plug the amp into any kind of remote triggered outlet, like the Ni... 
can mundorf supreme caps be used for AC filtering
Chrissain, you know that "AC rated" has nothing to do with the capacitor manufacturer's AC voltage rating right ? I just want to be sure we are on the same page. When we talk about "AC rating" for noise suppression use across AC hot and neutral, w... 
can mundorf supreme caps be used for AC filtering
I have used Audience's Auricaps for across the line AC filtering for more than 6 years without incident. The Auricaps failure mode is open, posing no short-circuit/fire risk. I don't know about Mundorfs. I would at least investigate the failure mo...
