power amplifier

Hey everyone! I brought my M-4000 out from hiding to do some maintenance and cleaning. I haven't seen many HQ photos of the internals online, so I was more than happy to take some and share. These amplifiers are really something special. Everything oozes quality, from the beautiful VU meters, to...

Hi, I have no reason to NOT believe an audio technician, but he told me that running a cooling fan on top of a Yamaha M-80 power amplifier could short out the transistors because of the sensitivity of the bias transistors to air currents. Is this true? I'm asking because I like the thought of...

Not sure how this adventure into Kenwood started but just picked up a couple new to me L-07M amps today. Letting these warm up before I see how they sound.

To many listeners, JBL 120Tis probably won''t pass as "reference speakers", but they are my reference speakers nonetheless. At least they allow me to recognize the difference between amplifiers. When driven by NAD C375BEE, for example, the bass sounds very strong and punchy, but they also sound...

Hey all I just picked up an Adcom GFA 5400 2 channel power amp from a thrift store for $5 dollars! Crazy cheap. Anyway it powers on but I cant fully know if it works till I hook it up. So, I am wonder if my Pioneer SX-626 can connect to it via its Pre-out/main in jacks that are jumpered...

Hi. I have a Music Reference EM7 5 Watts per channel tube SET power amp that I would like to match with a tube preamp for my Klipsch Cornwalls. I know that the Music Reference can also be used as an integrated, but just want to use it as a power amp. Does the preamp have to match the wattage...

Hey guys, Its been a while but I'm starting a build on this guy and thought you might be interested. This unit was running when before I received it, but things are never that easy. When I powered it up there was an immediate smoke storm and it popped the 15 amp fuse. Challenge accepted.

Hi everyone. I am new to this forum so be easy on me. I know just enough to get in trouble. Any speaker gurus out there, this is for you. I have a Phase Linear 400 II and I want to hook up multiple speakers. 4 pair to be exact. If you are not familiar with the Phase Linear it only has...

Hello everyone. thought I would introduce myself. I have been a Pioneer fan boy for many years. Purchased an SX-3700 based system back in 1980 (still works great). Always wanted to move up the food chain but could never justify the money. A friend gave me an SX-535 had to eventually replace a...

No profit, affiliation.... http://www.ebay.com/itm/182025159404?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Don't know if you guys think this is a bargain or not, but I'm posting here for you to decide. I got one the other day; works fine, good shape. These are old-school...

I have a Denon DRA-325R receiver (from the late 80s or early 90s) which I have used off and on for many years, and which is currently hooked up to our Blu-ray player for better sound during movies and shows. It still works fine, except that it will sometimes "reset" itself, powering off and then...
