Mario Coelho P Articles: 366 Schem.: 475 Pict.: 897 17.Mar.06 00:39	heath: T-4 (T4); Signal Tracer - Assembling/User Manual You aren't logged in. (Guest) 1 My Portuguese friend from Coimbra , Mr. António Manuel Rodrigues dos Santos sent me one Manual of a Heathkit T-4 with intent to present it here in Rmorg. It includes several photos, schematics, instructions, and so on. Nevertheless I notice that: -This Manual was pressed in 1959 -This T-4 is named VISUAL-AURAL SIGNAL TRACER MODEL T-4. - Here is shown one tube 12AX7 instead of one ECC83 as is indicated in Rmorg Model's page. This Manual was edited by HEATH COMPANY , subsidiary of Daystrom Inc. in BENTON HARBOR, MICHIGAN. I would like to know if this one is the same Heathkit model T-4 presented here in Rmorg's page before starting uploading date. Do You help us? Regards Mário Coelho

Now I found that there is another T-4 in Rmorg. (Model ID 79577). http://www.radiomuseum.org/r/heath_visual_aural_signal_trac.html Photographs and schematic were also already uploaded there. Well, the work was already done. So much the better. Best Regards Mário
