Title: ART-13 Special power connector... Post by: ART-13 on December 13, 2009, 07:29:11 AM Hi,
Does anybody knows the conversion between "letter" numbering and "figure" numbering ? I own a ART-13 with an external AC/DC power supply with different power plug... It is not the common U-7 plug...it is a plug (female) and socket (male) numbered "A to M" (M is center pin)... Who knows about this configuration ??? Iīm sure, there is no modification done on my ART-13... 73, Art HB9DCO Title: Re: ART-13 Special power connector... Post by: KC4VWU on December 13, 2009, 11:05:52 PM I'm really suspecting that it has been changed. I can't really tell by the picture, but are there a few pins that are larger than the others to handle heavier current for filament supply? The U-7 connector is usually so hard to find, and expensive when possibly found, that someone may have made use of a more commonly found connector pair.

If I understand correctly, you have the power supply -- plug her in and measure the voltages. This will give you the answers. I've got a manual for this beast; let me know if you need some more info. There is a nice piece in Electric radio a few years ago. You may want to get a copy of the magazine. Click on the link here on AMfone and search for the month(s) needed. There was a missprint in the main piece, the next month had a correction. klc Title: Re: ART-13 Special power connector... Post by: ART-13 on December 14, 2009, 02:54:09 PM Hi all,
Thanks very much for your help... I donīt know if somebody has modified in the past...see pics for better understanding... Yes indeed, I plug and measure all the voltages... The only problem, the story with +plate meter and -plate meter etc... We rewired the external powersupply (shipping damage), and we are not sure, if all is correct...the plug we didnīt remove... If somebody has a manaul with this connectors installed, I really like a copy, please... Where I can find the informations: AM phone...show me the way...Iīm a greenhorn...hi Electric Radio...I just registered...but where I can find... Title: Re: ART-13 Special power connector...
