    Mark Levinson No. 334 Acquisition and Questions

    The thing with the electrolytic capacitors is real but not an emergency. It's usually very expensive to do a full recap to an amp like yours. Consider it down the road if you want to keep if for long.

    Mark Levinson No. 334 Acquisition and Questions

    As a technician myself, If it plays fine, the the DC offset is ok and the heat the amp produces after around 1/2 hour is warm but not to the point of burning your hand and is even in both sides, I'd not worry about having it checked.

    Onkyo a809 integrated amp

    I just fixed one of these. It's fine, a decent amp, nothing to call home about.

    Why can't any amp drive any load at low volume? Or can it?

    Any other opinion?

    Why can't any amp drive any load at low volume? Or can it?

    I think that to the amp to send a lot of current there need to be a voltage (signal) level to maintain. And if it’s within it’s capacity, and according to my calculations it is, there should not be any problem. But something tells me that it’s not that simple. Infinity Kappas are super low...

    Why can't any amp drive any load at low volume? Or can it?

    Hi to all! Sory if this is too technical but I was bench testing an amp that was capable of delievering 33 V into 4 ohm load. According to my calculations, that is 272.25 watts (P=V^2/R). There should be 8.25 amps (I=V/R). Nice. Now the question. What if I have a nasty speaker thad drops to 1...

    I think it’s not possible.

    Harman Kardon HK770 Thread

    Hi! These are my HK 775 monoblocks and the rest of the series except the preamp. The power amps were restored and upgraded with non electrolytic caps where possible. I really like them. The volume pot of the preamp drifted it's value and caused a very nociceable channel imbalance so I replaced...

    Preamp recomendation Rotel maybe or...?

    Hi! I'm looking to upgrade my preamp. I currently have a Parasound P3, although happy whith the sound it has bad S/N ratio, i can hear the hiss in the background when close to the speakers... and as you know, once you hear it, you can't unhear it... My requirements are: -Digitaly controlled...

    What do these caps do in the circuit? Worth replacing?

    Thanks! So the best option is to replace them by high quiality low ESR electrolytics? No point in going film?

    What do these caps do in the circuit? Worth replacing?

    Greetings to all! I'm upgrading a pair por Harman Kardon HK775 mono amps and I'm replacing the caps in the sgnal path with Wima caps. Is it woth replacing the caps I mark on the schematic too? What do they do? I haven't seen caps like these in other amps I've worked in and not sure if worth...

    Pioneer SA-1000 Hum help

    If there is AC on the chassis post and there is continuity between it and the volume pot ground there should be AC on it too, right? I'm thinking it was an electromagnetic induction problem but could be wrong.

    Someone messed with it before. I'm going to fully recap it next.
