Just a couple of notes FWIW, to give credit where it is due. Minutes after posting a request for info I received a phone call from Kevin at Tritronics to let me know he would send the copy of the schematic section that I needed. This is not the first time that this has happened. Like all suppliers the order takers occasionally screw up, but they are quick to make up for it and the support they give is very good. Also, for those who do not use it, their web site is one of the best for looking up part numbers and checking availability. Also, sent my Fluke 79III in for service and got it back quickly, warranty repair (lifetime warranty) looks like they just sent a new unit, with batteries and fuses. They are not cheap but their support is great. I had dropped the meter once before and ordered a display and it only cost about $14. ------------------------------------------ To REMOVE your email address, click here: http://www.tech-assist.org/unsubb.html To CHANGE your email address, click here: http://www.techassist.net/forms/change.html ------------------------------------------ ***NEW*** Tips Added Instantly!!!*** Submit Repair Tips here: http://www.tech-assist.org/secure/tip/
