That town appears to be a haven for audio con men. The old Tek scopes are either too much work to keep going, or have mostly been used so heavily they are no longer usable. There are no more parts for DESIRABLE Tek scopes! Tek has not made an actual oscilloscope in nearly ten years and the last ones (the TAS series) were crude and nearly unusable. Large quantities of certain parts do exist-because either those are the parts that don't go bad or they are for stuff you don't want anyway. Actually, old Tek scopes have some great parts that lend themselves to happy employment in some really nice tube designs . . . . Indeed! ;-) The power transformers from the older tubed beasts are great for projects,if you can find any info on them,or else sit with the DMM and a pencil for a while untill you've got it..(a variac is helpful too!) I scrapped one that was beyond help,along with a HP that I couldn't figure out,tried/tested everything under the sun,finally gave up. Tons of good tubes,sockets,etc. in there too! I've got a Power Transformer out of an old Tek Scope - 545 I think or maybe an earlier model. snip I think that's the model that one of mine came from(tranny#120-120)..I've collected 3-4 big Tek trannies over the last few years. I'm sorta looking for another Tek tranny for my projects,marked 120-296 (from Tek 564's),if anyone has a spare. I'm thinking if I can find another,the pair will make nice power trannies for a couple of PP EL34 monoblocks. ;-) |
