marantz 2250 reciever lamps
I have some lamps out in the front panel of my marantz 2250 reciever -
I got an led number and source from a post but I'm not sure how to get at the lamps - it looks like the front panel comes off by 4 hex-heads on the front - anyone done this before I start tinkering ? |

I don't remember that particular model, but IIRC all the Marantz' of that period which I did work on required removal of the cabinet in order to access the lamps...usually four screws; two on each side...maybe one or more in the back. I'd try that before I started futzing with the front panel, which usually entails also pulling off all the knobs. jak |

I had the cover off already but didn't see any easy way to get at the
lamps from inside - looked like major surgery which I'd hoped to avoid |

Trying to go in from the front will be even more major. Welcome to the

You need to replace all the fuse lamps, the ones that work now won't work when you reassemble it. The lamps are accessed from the back. Move the socket plate backwards and use a hemostat to pull the bulbs out and a flat headed small screwdriver and hemostat to install the new lamps. It isn't a fun project but with care it should go ok. Chuck |

Thanks to all for the input -
The unit plays great and I'm reluctant to start moving a lot of wiring, etc in something this old so I''ll live with some dead lamps at least for now - if/when something else forces me inside I'll take a shot at the lamps |
