channel selector? I just bought it for a spare. #medium-smiley-013# That looks like the one. The bad news is that it's not pin for pin compatible with the original black switch. Some cuts and jumps will have to be made. Hopefully the instructions included will illustrate what has to be done. |

Cool. If you were going to have a mint/original 201A with a working "Black" selector rebuilt, would you just have this one put in while you're add it? I don't know how long these "Grey" units last.

I'm not sure if it's the black or grey selector that lasts the longest. I know that there have been discussions on the subject and there are some super great techs on this board that can set you straight. It's a shame that the D201's and the "A" models have what seem to be design flaws from what I've learned from reading posts about them. Resistors that aren't heavy duty enough, trouble with the connecting pins on the various boards that corrode and cause trouble, circuit traces that lift, etc. I bought a new D201 when they first came out. It was an amazing radio. I'm even going to say that I think that the radio was more sensitive on receive than the Brownings and I'm a hard core Browning freak. Just the looks of those Trams tell you that they're real radios. Anyway, if you're having your rig rebuilt and don't replace the tuner with the right one, it's bound to fail. I think that it has to do with Murphy's Law! I know that this doesn't help you but I had to comment. Good luck with your radio.

It would fail within months of purchase, depending on how much of a channel changer the operator was. The gray switch is a much better part and should last for a much longer period of time. I also agree that the Tram, while a supurbly performing radio, was not designed very efficiently, and really should have had another power supply voltage somewhere around 100- 150 V to use for all of the small signal stages, rather than dropping the 400V main supply down with power resistors. Those dropping resistors ran very hot, and their values would change after many hours of use. That's why a total D201 restore is so parts intensive, if you want to do it right. The Brownings seem to weather the years much better....... |

I will replace the working black selector with this new one when the radio is rebuilt. I have the feeling the stock selector will go south as soon as I get it back from the rebuild. These radios are expensive, but this 201A is a gorgeous rig that has had little use...stock tubes, no mods, looks new, and runs XLNT except for the cold blooded attitude from the typical age problems. What's $1K or so if it stops the spending.

But, after years of doing otherwise, I've had many years of success in talking myself into not fixing something that ain't broke. 73. |

Ouch $225 for a switch.  I should go into the tram switch building business. But of you love your radio I understand. I have poured allot more than that into my rebuilds! |

Ouch $225 for a switch. Yeah, it hurt. The thing is if I never get a chance at another, I'm gonna wish I bought it and kick myself in the butt. I play with V8 Vega's and learned a long time ago that if you think you want it, might need it, or just know it's hard to score...buy it. |

The synth board will have to have cuts and jumps made to the proper pins on the switch. It could be a little labor intensive which will translate to more $$$$$$ if you aren't technically inclined yourself. |

Yes, sometimes we pour $ into radios that we shouldn't. Other people don't understand why. But some things are worth the effort and the $ to keep them alive. Classic radios and cars, gotta love em. ;D

I'd give the switch to the tech doing the rebuild for him to do the install. |

I can't wait. |

That is one thing I would not change on that radio if it isn't broke.
If your channel selector is working use it.
That part is worth far more in the bag! And who the heck knows you may never need to use it.
