Inside a Waldorf Microwave II

via Chris on the Waldorf list.

"As you can see, there's not much in it. That got me thinking whether it wouldn't be sensible to move the dreaded external power supply into the case or even replace it with a normal internal one with a proper IEC-60320 C14 cable plug."

  3. Checking on the Waldorf list. One word of caution came in: "Can't make it out from the pic, but that side is traditionally the power supply side of Waldorf stuff. Nice heatsink on it.. Possibly a voltage regulator (I know the two large heatsinked ones are) If it's burned, there's a reason it's burned. Replacing it could harm the rest of the board even more if he doesn't find the reason it burned in the first place.

    I melted my blue Q keyboard trying to install an extra voice board. (luckily I have more Qs). Something to do when I get off tour this summer.."

  4. There is a service manual with schematics, but it refers to rev 3.2. Th532ere are quite a lot of revisions. Major changes like 56303 66mhz vs 56303 80mhz in later versions - that has an impact on the voice expansion. Also nicer emphasis circuit on mid-revs and philips ne5532 vs texas ne5532. Roms can fail... but you can program new ones - check upper 88c4 and lower 4ace.
