    Marantz 2215B Parts list

    Hey everyone! Working on a Marantz 2215B for a friend. It's in really rough shape. Power amp has a couple of blow output transistors, and the tuner section loads the power supply. Couldn't find an exact culprit in the tuner section, but I've come across at least one leaky diode. All the caps...

    My Scott LK-72 Restoration -LONG Journey But Not There Yet

    Back around 1995 I saw a "Free" post in HP's internal ads for a Scott LK-72. Luckily I was the first to claim it (a gold-face, neatly built unit, in mostly pristine condition). It came with original instruction book and a note saying one of the 0.1 uf was leaking and needed replacement. As...

    Kenwood KR-3130 Replacement Transistor

    I'm in the process of my first vintage audio restoration - a Kenwood KR-3130 that was given to me by my dad. The right channel didn't have any sound initially which I traced down to a bad Q16 transistor (2SA565). I switched this one with the left channel (Q15) and now the right channel works...

    Clipped output in 2235B at about 75 percent volume.

    I recently acquired this receiver which was dusty but otherwise functional. No appearance of any service performed. I cleaned the unit internally and Deoxed the pots and switches. Under power the unit has a minor 60 Hz hum on the phono inputs but the aux in is quiet. Those are the only two...

    Restoration: worth it to replace internal wiring?

    I get replacing the caps, but is there really any measurable reason to bother replacing 22AWG w. 16AWG in a 40+ year old pair of loudspeakers? Does the extra beef really improve things?...I tend to doubt there's any real improvement after doing this, but I don't know ****, so wondering what...

Well, I fell off the map and the original thread kind of spiraled out of control, so if at first you don’t succeed, try try again. There she is. A little dirty but was neatly tucked...
