New FT-101ZD owner w/ issues: NO TX/RX, digital display won't change freq ..

 

Hello everyone from Colorado!?

For years been wanting to get a FT 101.? My grandfather had several 101's since the 50's but when he exited the hobby 15 years ago, sold them all.? To me the 101 is a handsome rig and remembering my grandfather operate his brings back great memories.?

I found a FT-101ZD in FL several days with some issues.? Its SN is: 9F-060716 which makes it an April 79' rig and a MK0 "ZD".? The radio powers on and "tubes light" but with no TX or RX.? The display stays stuck at 0.200.0 and won't change frequencies either. I am still waiting to receive the radio but I would like to get a "head start" ..? Although considered a "hybrid" radio, it still is HUGELY mechanical. My first thoughts are perhaps the rod/linkages might be busted.. * maybe *.

I have ordered the service manual and owner's manual as well and waiting on those as well. Might you fine folks here chime care to share your thoughts, experiences etc.? I would certainly appreciate it.??

Needs a link in ACC socket on rear panel to transmit.
You will need an 11 pin plug.
Link pins? 1-2 to get the heaters to power.? Tube will no light otherwise.

If the RX gives sound output and the tuning knob (VFO) will find stations - investigate the display unit.?
If noise out but no stations check the RF input fuse (bulb) then the oscillators.
If nothing out? not even noise check the audio stages first.

BEWARE:? The HT (900 volts dc) is always ON even if the heater switch is OFF and in the transceiver is in receive mode.? 900v and 300v present on the underside of the chassis and in the PA compartment.? Beware of the 300v on the feed through capacitors on the driver compartment.? It bites !? 900v present on the RECT B board and transformer tags.

Good Luck

Hi Greg,?

Appreciate your input.? Do you know of a commercially available 11 pin plug/link by any chance?? I am looking through the owner's manual online for the 'ZD' and cannot find a mention of a link or plug that enables the RX/TX or use of the digital display.? The text description of the display only talks about the wiring within the chassis but no plug/link.? Perhaps I am not seeing it.? Will investigate further into this.??

10-4 on the HV present within the chassis, I'll treat this just I do amplifiers with the upmost caution to ensure the HV is dissipated and the "one hand in pocket" technique my grandfather shared with me back in the day.?

My understanding is the tubes DO power on though.? Which is odd if a link/plug was needed.? Would you mind pointing me in the right direction within the manual or the schematic?? Thank you, sir!?

Alrighty Update-? ?I found the ACC plug. Was staring right at me.? ?Will report back on the progress , thanks again!?
 

Page 6 of User Manual and page 1-8 of Service Manual both show ACC plug with link

Note:? It is very easy to touch the feed through caps with 300v on them with a finger at same time touching the chassis !
