Well, this is embarrassing.

A little history... I had been looking for a decent-condition Warrior for a while.  I found one in September of last year in Florida at a price that seemed about average for that amp (not an earth-shakingly great deal, but not bad either) so I figured I'd grab it and put it on the shelf until I could get around to integrating it into the station (see my page on QRZ... it's going into the rack above the Marauder where the rack-mount Collins 30L-1 is now).  Now, 14 months later, I'm finally getting around to it.

The seller suggested, and I enthusiastically agreed, that he remove the power transformer and swinging choke and ship those separately.  What I didn't know is that he also removed the filament/bias transformer, which mounts inside the chassis and so is not in plain view.  That's fine, but now I can't find the transformer, and I'm not entirely certain I ever received it.  We had never talked about removing anything but the plate transformer and filter choke, so when I received the amp and inventoried the parts, those were there and I figured I had everything.  Now that I'm in the process of putting the thing back together, I see that the filament/bias transformer is missing.

I contacted the seller last night and he says he sent it with the rest, so OK, I'm willing to accept that I just lost it.  Regardless, what do I do now?  Any suggestions from any of you for replacements?  Fortunately there is plenty of room (lots and lots of room) inside the chassis so shouldn't have too much trouble finding someplace to put whatever I find.

For reference, the transformer is 115 VAC primary, secondaries 6.3 VCT with current sufficient for four 811A filaments, and 10 V at low current.

Thanks...
