MARANTZ 2225-----PARTS KIT FOR PREMIUM RESTORATION
I have serviced all the popular Marantz receivers since they first came out. I see them frequently now for restoration work so I know exactly what they need at this time in their lives. Service needs change over time. When a lovely piece like this gets to forty years old, it needs some general help. Most of the 2225’s that come in for service are not outright blown up. They frequently work…..somewhat. They are, however, full of old capacitors, noisy signal path transistors, heat fatigued voltage regulators, and bad relays. Of course, they are in dire need of cleaning and alignment. This sort of job can be undertaken by a qualified technician or a serious hobbyist. Of course it helps to have the precise parts needed in hand, along with their precise locations. This kit is meant to supply that need. It is not a “paint by number” for those with no experience, but with moderate test equipment and some technical skill and patience, good results can be had. Recommended Test Equipment: Multimeter, Variac (5 amp or greater), an oscilloscope can be useful if you need to trace lost signals, but is usually not needed. The service manual is invaluable and may be had on line. Try HiFi engine. The kit includes the standard and usual parts required on the following boards. The parts will be in individual bags for each board. There will be a list of parts for each of these boards with schematic designation. There will be a procedural tip sheet. You will find the instruction sheet to be very useful as it will contain a lot of information derived from the service experience on this model for forty years. This kit is not guaranteed to solve any and all problems. If your unit has an outright defect, it may be something other than the standard and usual. Great care should be taken to get polarities and transistor basing correct. Careful and tidy workmanship pays off. Be prepared to trouble shoot if you make a mistake or have additional problems. Phono Amplifier Assembly. P400 Power Amplifier Assembly. P700 Power Supply Assembly. P800 Tone Amplifier Assembly. PE01 Unregulated Power Supply. C003,004 The capacitors in the kit will vary but will be selected from the following: Power supply applications will be mainly Nichicon, or Elna. On the other boards, they will be Nichicon FG, KW, FW, KT, VZ or Elna Cerafine or Silmic II. The semiconductors in the kit will be well vetted substitutes for the original Japanese numbers. I have been using all of these parts for quite some time, and they perform very well. The kit does not contain lamps as some folks want incandescent and others want LED so lamps should be purchased separately. The kit does not contain tuner section parts as tuner work should only be attempted by tuner experts. The kit does contain the power supply filter capacitors. When all of these parts are replaced, and the unit is cleaned up and alignments are done, reliability is enhanced, and the sonic quality is astounding. They knew how to do stereo back in the old days.
