| Modifying my Mark Levinson 332 for a unique visual experience @hsam Very Nice. May I ask where you got parts from.(Caps etc). I got a 332 that needs a overhaul. The main caps are available from Mouser.comThey are about $85.00 each. Part No. 598-3186GJ503M125DPA. They are not exact replacements for the orgin... | |
| Mark Levinson has odd choice for cap upgrades in one of their service bulletins. Why? @imhififan : Due to voltage rating of those caps? Are they working on same voltage or the caps working at lower voltage on current gain board?I took it apart today to compare the caps on the current gain and voltage gain boards....they are the sa... | |
| Mark Levinson has odd choice for cap upgrades in one of their service bulletins. Why? @imhififan Some pp cap has >50% voltage derating when operating temperature over 85 ºC , that could be the possible reason Mark Levinson recommend replacing them with Ceramic X7R .01uF @ 200vI could see that. So you prompted me to look up derat... | |
| Mark Levinson has odd choice for cap upgrades in one of their service bulletins. Why? @teo_audio; Why pull your post?I get the argument from both sides and I really appreciate all input. Dialogue like this challenges my thought processes and possibly will answer some questions for others that casually read this thread.Since ML has ... | |
| Mark Levinson has odd choice for cap upgrades in one of their service bulletins. Why? I agree with Erik. These are small value decoupling caps. So for those unfamiliar with the amp here are some images and schematic clips:This is my beloved 332. The caps in question lay horizontally just beneath the top cover.https://drive.google.c... | |
| Mark Levinson has odd choice for cap upgrades in one of their service bulletins. Why? The answer indeed seems to be heat, but it’s also important to understand the application. That is the part that is troubling me. Heat is a factor that is well known in class A amps. Even though we are talking small capacitance values wouldn’t we... | |
| Modifying my Mark Levinson 332 for a unique visual experience Thank you all for your positive feedback so far. Anyone who has seen it in person was really impressed as well.I am glad I took the risk and will be lurking in the shadows waiting to find the next one to do a matching makeover on! | |
| Modifying my Mark Levinson 332 for a unique visual experience @zavato ...I stand corrected. I meant 20+ years. My mind is stuck in the era of the Model 23.@jafant ...Currently the ML332 sits comfortably in my project studio. It has replaced a Carver amp which will soon earn a much deserved tear down and rec... | |
| Modifying my Mark Levinson 332 for a unique visual experience Thank you all for your kind words! I bought it online with the knowledge that it was not functioning. I don't have any history on the amp but I do know there were very crude attempts at repair which probably caused more damage. The vaporized volt... |
