First let me apologize for this likely being in the wrong place or otherwise somehow mis-posted. Those who remember me from the arcade game newsgroups may well remember that I never had a very good grip on posting procedures and protocols. That said - I acquired 2 Tek 7704s, a 7834, 7704A, a pair of the 3 slot versions of the 7704, model number escapes me at the moment, 7623, 7633, and a 5103. At the moment none of them work properly. The 7704A and the 7834 both worked properly until I used them to test a batch of plugins and each was damaged by bad 7A26 vertical amps. I checked the power supplies on both and they are ok. I don't have the understanding of scope operating theory, the patience, and most of all, the desire, to fix these. In addition I do not wish to ship working scopes of that weight and bulk; getting to be an old fart now and don't want to haul a packed 45 pound scope up my cellar stairs to the porch for UPS. So - all but one of the 7704s worked to the extent of being able to verify that HV was present and the CRT had usable brightness; most had either vertical or horizontal deflection. The 7834 was working, the storage buttons produced various changes in the phosphor. All I believe have decent complete knob sets except for one of the 7704s. Holler if you need anything and we can work something out on price. If you are willing to pay the extra shipping I will sell the 7704s if I can ship them in 2 pieces, separating the display from the acquisition unit. Hope this finds you all safe and healthy - stay that way :) Art - From NY _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
