Hi all,
I wonder if there is any interest in a service that would be recapping/restoring/upgrading the 9001? Pretty much what QB was doing, without the . . . how should I call it, problems with delivery?
I'm an audio engineer, with a 33 year career in pro audio. I founded and owned the 2nd largest PA company in the country. I have designed and built lots of gear for pro applications, everything from electronic crossovers to a big 40 X 16 mixing console. I have been playing with the 9001 for a couple years now. I have a couple of surround systems set up, HT and a quad setup. I have improved on the holy grail alignment a bit, and worked out some tweeks for the amplifier section that deal with the differential amp part of the outputs. I'm pretty good at working on electronics, I've been doing it since I was 8, I was a ham as a kid, then worked in broadcasting, have or have had a 1st class FCC license and an Extra class ham license.
I'm retired and got hit pretty hard by the '08 crash. I have two sons in college, and could use some extra income. I love working on hi fi gear, which is my winter hobby, and my summer hobby is airplanes, I have built/rebuilt 3 airplanes. I had thought of offering this service before, but QB seemed like a great guy and I wouldn't have felt good about competing with him when he had worked out most of the mods and upgrades.
I've been helping a guy in Singapore repair his 9001 over on the AK list, and someone reading the thread PM'd me and asked if I would do his 9001. He explained to me what has happened with QB, and that has led to this post. I'm working on a 9001 right now, and I will be doing this guys unit as soon as he ships it to me.
So, would any others be interested in this? What has happened with QB is interesting, cause I have seen it before. I've been a Fisher fan in the past and there is a guy who used to work for Fisher, who has gotten himself into the exact same fix as QB, lots of upset people, and he doesn't return gear or money, or emails. Go over to the Yahoo Fisher list and you can read all about it. He was called the Fisher Doc.
I would never want to end up in that place, and the way I would prevent it from happening is to only accept gear for restore on a reserved place in the lineup kind of deal. I would control people shipping to me, so that I would only have a small backlog. I do not have the space to store a bunch of gear waiting to be repaired anyway.
I can basically offer all the same service QB was doing, plus a couple extras. I was never aware of his pricing but from what my first customer has told me, I would be willing to just start with the price he has told me, that he got from QB a couple years ago, and see how it worked out. The 9001 is the biggest, most complex receiver to come from Japan, but I can tell you that it is a piece of cake compared to a big mixing console, which has 20-30 times as much electronics in it.
I can do
Complete recap with Nichicon KW and KT caps in the signal path, others for power
Add Polypropylene caps where it makes sense
Change out the fusible resistors
Pin and resolder the 4 ch board
Power supply mods
The holy grail alignment and resistor removal
Offset and bias
Differential amp tweek, balance, and mod-- in outputs
Disable the 2X power switch, but I don't recommend it
Add an RCA connector interrupt point just before the power amps
Also do basic repairs
If you have any thoughts about this, I would appreciate it. Please jump in and tell me what you think.
