2225

    What are the output specs of the transformer for Model 2225 ?

    Does anyone know the output specs for the 2225 transformer? The service manual shows three AC inputs to the P800 power supply board, but I don't see any specification for their voltages. I can measure them on the unit as well, but would like also to compare those measurements to a spec.

    Diode bridge substitution on 2225 P800 power supply

    I’m trying to identify modern components to replace diode bridges H801 and H802 on the power supply board (P800) of a 2225. After much searching, I can’t seem to find any information about these components’ specifications. The part numbers are: H801: HD2001508; description SS-3R H802...

    Mechanical drawings of Marantz chassis

    Is anyone aware of the existence of mechanical drawings of Marantz receiver chassis? I’m doing some custom work for a 2225 and 2325 and want to ensure proper fitment, and engineering drawings (or the next best documents) are preferable to reverse engineering. Moreover, I don’t have physical...

    2225 with poor FM reception

    This is my first attempt at troubleshooting a receiver. FM has weak reception, and it is unable to activate stereo. Would a recap of P200 help or would this be an issue with the transistor(s) on that board? What should I attempt to look at first?

    First Receiver recap/restore, need advice

    I always resisted working on receivers mainly because I don't have the proper equipment (or knowledge for that matter) to align them if I have to. However yesterday I got this beauty for a reasonable price and couldn't resist. As I opened it I noticed it has never been worked on. It is in real...

    Marantz 2225 Phono crackle

    My 2225 has recently developed a crackle on the left channel in the phono section where the sounds starts t break down and eventually just goes away. I tried a few basic troubleshooting steps like swapping out phono carts, checking cables, moving the phono cable from left to right, deoxit'ing...
