Good luck for the relay.

Thankyou Jacques.? 6883B is a far better price and not much re-wiring to do under the final box.? Now if I can find a source for the relay; several places the relays are listed but no stock.? I will keep trying. Nice transceiver, I had never had my hands on one until this one came in for repair. 73

I guess you guys know this, but I was told the 101 output tubes are the sweep tubes used in the old tube TVs. ?I suspect it was a smart move as Yaesu probably figured these tubes would be around for a while.

Just a note to ask if anyone is using 12 volt versions of the 6146B tubes in the "ZD"??? The 8298As have served well but getting pretty weak.

WOOT!!!!!!!
?
Diodes have been replaced....what a chore that was. And the radio is receiving again and, more importantly, not popping capacitors! ROFL.?
?
However, it needs more work and I believe discretion is the better part of valor at this point in time. I am going to reach out to Lee and request his services.?
?
Some things are better left to the professionals. Besides, I did replace all the caps, and got it back working again with a nudge from Lee. I'm gonna take a victory lap and call it good.?

Dave,

Lee had me check the diodes on the rectifier board (PB-1076B). Both D6&7 were cracked. They control the 13.5vdc circuit. So, replacements have been ordered. Hopefully this will fix the problem and this rig can be back up and running again very soon. ?I checked all the other diodes on the board and they all checked out good.?
?
Thank you again for Lee's contact information. He was/is very quick to reply and I greatly appreciated that!

I have run out of ideas at this point as to where the problem lies with the 101B. I'm at a point to where I need someone a whole lot smarter than I to resurrect this old lady.?
?
I have reached out to FT101repair.com but have not heard back from the gentleman and am wondering if he still repairs 101's.?
?
Soooooo, If anyone can recommend a person that does repair them, I would be grateful for their contact information. I so very much want to get this radio back on the air.?

I was so close a week ago and now much further from the end than the beginning.?

Hi-rez full size scan schematics

 

Hello there.
?
I recently inherited a manual and a full-size fold-out schematic of the FT-101E.
?
I went to FedEx Office and had a 600dpi black and white scan made.? It's a little over 2Gig in size and zooms in and out really very nicely.? I printed a couple out and had it laminated in clear so i can use my dry-rease markers on it.

If the team figures this is useful to upload, i will.? Otherwise, email me chris@... and i'll send it to you.

Re: Early FT-101 problems

 

Check the bulb that is in the front panel plastic escutcheon as well, it illuminates little dial indicator triangle.? It could be shorted.? I found mine cracked.

Wanted to let folks know that in addition to being a ham with an FT101B, I am an artist and a printer and own a 44 inch wide photo color printer. ?I also have software that can blow up images with no loss of detail to very large sizes so if any of you need prints of circuit boards, electrical diagrams etc. that you want blown up and printed I can help you with that.

Well,?
?
So close and now not so close. I was checking voltages on PB-1315A and heard a POP. 2 caps C11 and C12 blew. I replaced them and they blew again.
?
Now I am in a fallback position as I can go no further in my testing until I figure out what blew C11 and 12. Thankfully, I did not have the heater switch on. At least I hope that is a good thing.
?
Anyone experience this condition, I am happy to hear your results. So far, maybe T12 is bad..dunno yet. Gonna let the rig set for a bit before I dig back in. ?I’m bummed as I was so very close in getting this rig back on the air..
?
Bummed in Nevada…..

Serial Number Again

 

Hi All,
?
New to the group!? I picked up a FT-101 off of Ebay from a Japanese vendor and have a question about decoding the serial number.
I know this has probably been hashed over many times but I am unclear about one of the digits on the back panel label.
My unit has the following number:? 83D134146.?? I understand 3 is for the year 1973 and D for February, lot number #13 and serial number of 34146.? Please correct me if I am wrong.
?
My question is what does the "8" mean at the beginning of the back panel label?? Does it indicate its a Japanese domestic market radio?
?
Thanks much for any help!
Ed? KN6NZW
