1949 Admiral combo - looking for IF can
 

Part number is 72B42.

I'm restoring a 1949 Admiral combo - 12" Model 4H18. Video isn't getting through. I took the can apart - the resistor is good. I replaced the cap in the can and still no luck. Let me know if you have a parts chassis with an extra - I'd really appreciate it - or any other suggestions for troubleshooting. Thanks - Gary

I have the 1950's Admiral 24R12, which is a model or two newer. I have the Sams but your part number isn't used in mine. Do you get sound (and is it an intercarrier set (sets that pick off 4.5MHz FM sound carrier off the video detector))? I would guess that the coils in your device are open. Sometimes the rosin used for tinning the fine wire of the coil will corrode and eat thru that wire right at the terminals inside the can. If so carefully reconnect the fine wire.

Be aware that your set probably uses an IF frequency of 20 to 26MHz (like mine) and not the more modern 41 to 47MHz IF. So a transformer from a modern set thus wont work.

it crosses to a Thordarson part 17-1002 note mounting different
The 4h18s/sn use the 17-1002
the 4h18c/cn uses 17-1063 (admiral # 72a83/1 )
the models that us the 17-1002 would be 4h15s/sn ,4h16s/sn,ah17s/sn,4h19s/sn,4h115s/116s/sn,4h117s/sn,4h126s/sn,4h137s/sn,4h145s/sn,4h146s/sn,4h147s/sn,4h155s/sn,4h156s/sn,4h157s/sn,4h165s/sn,4h166s/sn,4h167s/sn,8c11/s/t,8c12/s/t,8c13/s/t,30a4s/sn,30a12/s/sn/t,30a13/s/sn/t,30a14/s/sa/sn/t,30a16/s/t,30b15/16/17/s/sn,30c15/16/17/s/sn..I did back crossing in the thord manuals double check the number if you find any of the above. also note the above if had other suffixes had the other coil.

Thanks for the cross reference number, Doug, as well as the models that used this can. If an AK members have a parts set that uses this component, let me know!
