amplifier

Allright, admittedly a bit of a clickbait title as there was strictly no blood involved and the explosiveness of the power supply caps is only assumed at this stage - but I could really use some help over here since this is my first repair attempt. I purchased this Armstrong 626 amplifier (S/N...

I dedicate audio 40 years, I never disclose their topology until the last years. Here is one of my latest amplifier topology. http://www.federmann.cz/images/stories/Nf/HQQF/HQQF-55-503W-4-2_zapojeni-1kanal.jpg

A few years ago I blew one channel on my Cyrus III (SR 32151) and had it repaired by Mission. The problem now is that 1 channel of the amp doesn’t really work until you turn the volume up to about 11 o’clock when both channels snap back to near equal levels – using an attenuated audio lead to...

Hey guys, I have a koiiler xm7663 4-channel amplifier with a pioneer deh6000ub hu. The issue is that one of my channels doesn't output sound a low to moderate volume. However when I turn it up I get sound to that speaker but it is really nasty, distorted, and static-y almost like a blown...

Hi! I'm new to this, and i got here searching through google... i'm in a big hurry, so if any of you can help me, i'll be really greatful (sorry if my english is not very accurate) ... Long history short, i have a Marshall MS2 (a friend of mine's one), it fell and didn't sounded anymore, so, i...

Parasound HCA-1000 2 Channel Amplifier This is a great sounding mid-level amplifier with 2 X110 Watts of real solid power. The unit is in good condition, it has a few scratches on the top of the case from being rack mounted and 3 of the 4 amplifier also don't have feet (also from being rack...

I'm assembling a booster the one that uses input and output transformers and two mj2955 transistors. I bought a 100watts output transformer, but the diagram I have uses only 2 transistors. I have heard that when the output goes up to 100 watts the number of transistors must be increased to four...

OK So I finally got around to putting a direct input on the back of my Integrated Series 200 Playmaster amp. Initially this is so I can run my HT PC direct into the amp bypassing the preamp section, but still have the rest of the preamp switching available for other inputs. Basically I stuck...

Hello Everybody! I would like to see some pictures about the inside construction of the classical Classé DR-9 amplifier. I would appriciate, if somebody have an internal picture, and can post it here. For me is mainly interested, how the emitter resistors are connected to transistors, but, of...
