KNOBS HP1701 SCOPE
|
HELLO to the Group... Recently aquired a slightly damaged 1701 scope. The three knobs on the time base selector were missing, and all three shafts were bent..Through some subtle persuation, and lots of praying, I got the shafts stright. To my surprise, when I powered it up and turned a couple of knobs, a nice bright sharpe trace appeared......... Now comes my real problem...?? ?KNOBS?? .......... HP part #s ?0370 2173 ?0370 1129 ?01710 57404 Hoping someone has some idea where I migth ?find them or even a parts unit. (reasonable $$) Thanks.....?????? ...BOB...??? KD0IJI@... |

开云体育Hi Bob ?????????? Well done in getting the olde going. I have just done the same with a 1725a. It was received with no covers bent timebase shafts. Wiring looms cut and no power supply power transistors on missing heatsink. The main problem was a warped horizontal board to such an extent that the socketed main and delayed timebase boards thro which the switch shafts run was out of line. This made for very intermittent operation. It looked as though someone had got so fed up with this they had hit the timebase knobs with a hammer and bent everything. If you want I can photo these so u can make something on a lathe (1701 and 1725 knobs look similar). I clamped both timebase boards to the scope side member now its reliable. I wanted something to enable me to see pulses from a Geiger tube the old 545a was not up to it. ? ? Cheers Keith G0SKJ ? -----Original

Thanks for the reply... My scope the HP 1701, has three (3) knobs on the shafts that control 'Main TIME/DEV, Delay TIME/Dev, and Sweep Select'.? I beleive they were used on several 170x series up the 1707 model..? I've checked invetory of the usual old part suppliers to no avail... Hoping someone in the group my have something they will part with ,even a parts unit.? (reasonable $$$) Thanks Again..? ...BOB...? ? ?
