2010年7月18日 · The M90 has wonderful sound but the FH7 and 680 have a deeper, richer sound. The FH7 sounds wonderful with all types of music but can't reproduce the low bass notes like the 680. But it came down to this...when playing the 680 and FH7 side by side the 680 just has a little more clarity and makes the music sound a little better.

2019年4月13日 · In the JVC service manual "Supplementary" section, on page 2 you will find the "Mechanical Control P.W.B. Parts" diagram and on page 3 you will find the parts list. The components you are looking for are FR701, FR702, FR703 and FR704.

2021年11月4日 · The fact that JVC made last-minute changes to the deck board may be why it doesn't have its own page in the service manual like all the other boards do. JVC published it as a supplement, and only Superduper's scan has it. It's very crisp and you can see the final version of the board where they modified it to include the fusible resistors.

2025年1月28日 · My JVC M90 was all working fine after replacing one fusible resistor. That fusible resistor can be seen at the top edge of the mechanical control board PCB. A few days ago, I just brought out and when powered on it was not resetting with the clicking sound. I knew there is some problem with it.

2013年10月24日 · If you take the 100v power circuit & put 115 volts through it, 1.15 x 40w = 46w & 1.2 x 40w = 48w so my guess is the C versions are running 100v JAPAN power supplies for Canadian versions & JVC split the difference & labeled them at 47w....makes sense. If you apply the same logic to the M90, a C version would be 70w, SURPRISE!!

2015年8月4日 · Hi everybody! This is an awesome site and this is my first post. I've had the luck to find an JVC RC-M90 at my grandparents house. unfortunately, time didn't any good for it.
