Roger VE7LB All Messages By This Member #73 Hi Dave, Do you also have the 120 volt power cord? About your 40+ year old FT-101 high voltage capacitors. You should replace the two main high voltage capacitors on a 40+ year old FT-101. See eBay item https://www.ebay.com/itm/254527364032?hash=item3b43035bc0:g:CDoAAOSwyWheWysT (I have nothing to do with the seller). If they fail they can take out the power transformer. It's also a good idea to change out C13, the 80pf@ 1kv driver to final coupling capacitor.? Also C11 a 200pf @ 1kv in the driver plate circuit? Bad things can happen if C13 shorts. If you have scratchy controls and switches. The first thing I do with a radio that has been stored for a long time is exercise all of the front switches (especially the band switch) and pots end to end. Sometimes as high as 40 times each with the power off. Then I check to see what is still noisy and go from there. Most people like the Deoxit brand for cleaning switches and pots. Use care on the band switch - I use a toothpick and apply only to the contacts. 73 Roger VE7LB Group Owner

I have checked the rig out and it does receive and transmit and the pots and switches are noisy. ?I haven’t replaced any capacitors. ?Others have said replace all the electrolytics. ?I appreciate your providing advice for specific capacitors and sources. I had an old tube bass amplifier and had the?worst time getting capacitors with high enough voltage ratings. ?I actually blew some up with lower voltage ratings. ?Fortunately Fender had placed them in a metal box so they didn’t blow up all over the rig. ?It did make for a novel performance experience.

Dave VE3DPC All Messages By This Member #76 Hi Kenoli and thanks Roger for finding the a better SM Like the song goes “we only just begun “ My xyz and I are still unpacking and I have the boats and our cabin to winterize and I better also get a dipole up before the snow arrives!!!!? The restoration of The FT101 is going to be a winter project but the first project once my bench is setup. As far as caps go I’ve never had to many issues getting HV 500V caps but that was 5 years ago now so I’ll look were ?I got them and report back. I need the ac power chord and found a source on eBay with “locking “ tabs so might just go with that. Happy Thanksgiving es 73 david ve3dpc
