<br></div><div class="gmail_default" style="font-size:large;color:rgb(0,0,255)">I'm firing up my restored HL-2200 for the first time with a nice fresh set of tubes. Both the old tubes that came with it had grid-to-filament shorts (BANG and BANG).<br>
<br></div><div class="gmail_default" style="font-size:large;color:rgb(0,0,255)">I was careful when I rebuilt the tank. I installed an original SB-221 tank coil and carefully rewired it to the tank coil taps. Reinstalled the Tune and Load caps and the doorknobs and the parasitic chokes. Got everything cleaned up and looking like new.<br>
<br></div><div class="gmail_default" style="font-size:large;color:rgb(0,0,255)">I ran the tubes with no load for about four hours to cook them a bit. Decided to put some drive to them. Up to 200MA, and dipped the plate. Whoa! the Tune condenser had no effect at all and NO output, so I shut her right down and got out the Manual.<br>
<br></div><div class="gmail_default" style="font-size:large;color:rgb(0,0,255)">The "In case of" section mentions checking the rear bandswitch wafer to be sure it's set right. Well, it's possible that I didn't set it right, but I remember reading the part about making sure the wafer contacts Pins 6 and 12 only when the front wafer (input) is set to 80M. I don't have it apart yet, but will do that this weekend. That makes sense to me that the tank wafer might not be set right. The other possibilities are L7 on the input side being installed wrong, but I didn't work on any of the input wiring; it looked fine to me and original. Or, the T/R Relay might be smoked? I doubt that, because the transceiver still hears fine on Rx. Now, that doesn't mean the Tx contacts might be bad.<br>
<br></div><div class="gmail_default" style="font-size:large;color:rgb(0,0,255)">Now, with those two "BANGS" with the old tubes, it it possible that I might have lost one or both of the doorknobs? Or, maybe the inline choke going from the HV feedthrough to the big plate choke? I was able to draw Ip, so the metering is fine. Anyone have any thoughts on this?<br>
