    Advice - Schematic says 4.7uf 10V but...

    ... in there now is a 4.7uf 16V. Yes, I understand that I can replace the cap with a 16V instead on 10V, however while doing a recap on my Marantz PM 550DC amp, should I adhere back to the schematic and replace the cap with the 4.7uf 10V (also I have ordered that cap but I can get the other one...

    Help! DAC Suggestions for Cambridge Audio CXC-V2?

    Hello AK, I'm a bit of a noob to world of Hi-Fi. I started building my system about a year ago now. My brother-in-law gave me a JVC XL-FZ258 5-disc changer he picked up from an employer. It didn't look like it had ever been used, the price was right (free!) and it has proved to be a...

    Marantz PM 550DC - Sound/Output distortion?

    Hi everyone! I took a chance on an online auction in NZ for a Marantz PM 550DC Amp that was at a tipshop (like the recycling part of a rubbish dump) knowing that there probably was an issue. The unit's appearance is in great condition and I used Deoxit on the volume and balance knobs (the...

    Huge Marantz towers

    I'm searching for some information on a set of old school Marantz speakers. They were from the mid 80s to the very early 90s I would assume. It was purchased as a complete "home entertainment center" with a 27ish inch television. The audio section was individual components. The speakers were...

    Is my Marantz SR5004 a nice looking paperweight?

    Hi all! I have a Marantz SR5004 receiver hooked up to 2 McIntosh XD715 Loudspeakers (which sound amazing and I love so much I might marry). We use the system for watching TV and movies in our family room. It's pretty cool; you should come over sometime. Annnywho - over many months I've noticed...

    Marantz 4070 transistor substitute

    Hi all, currently repairing a Marantz 4070 can I use a 2sa970BL transistor in place of 2sa641 for h701-704? I’ve seen other posts that recommend bc556bta but looking at specs and what I have on hand I think the 2sa970 would suffice but I’m no expert, thanks!

    Wood Receiver Cases/Cabinets-How I Built a Few

    Here are the steps I took to build these wood cases: After exhaustive searches of the interweb I found only one relatively complete guide on how to build nice wooden cases for vintage (or modern) audio receivers.

    Marantz SR-92 / 96 or SR-XX units for 2-chan music

    Looks like I'm gonna end up with some B&W DM600S3s for my desktop speakers... while I love my Sherwood S-7300, I'm concerned it may not have the oomph for B&W (which are rumored to be power hungry). Looking around, I've found that both Yamaha and Marantz have very good reputations in their more...

    2220b - Dial indicator light - flickering

    The dial pointer lamp was dead in my unit (along with most of the other incadescents). I bought a kit from aliexpress, link. The regular LEDs work fine and the dial pointer lamp lights up fine. But there's a faint flickering. It's not very obvious, but thought I'd ask just in case. Any way to...

    I recapped this unit and after doing so noticed that the tone board doesn't work anymore. The bass, mid and treble pots don't do anything.

    Best crossover replacement for Lascalas

    I am going to replace the crossover networks on my 1984 AL crossover Klipsch Lascalas. I have gone through the old threads and they (for the most part) have left me a little dizzy. Currently, neither one of the K 77 tweeters are working at all. So, before I replace the tweeters I think that...

    Why do Speakers Sound Brighter As Volume Gets Louder?

    Beyond a 'normal' listening level (maybe 75dB?) music start sto sound brighter and harsher with more volume. Theories so far include: - The speakers need more power to balance frequency range at higher volumes - The human ear (or at least my ear) is more sensitive to high frequencies and...
