Seems I also need to reassess my rule of changing the "To" line first when passing on an email. This was meant for my nephew but neverless Im sure others may have dug out their old RS iron to give it another try. Before the Hakko 470 I preferred and iron and plunger type sucker.
On this same subject, I see similar looking tips for the Hakko from cheaper similar style desoldering guns and wonder if they fit. Hakko tips are 20 - 50 bucks while the others a just a few dollars. Anyone tried them and can say how they fit?

Hey Mike, you know that iron I have with the red bulb. Ive used it but perhaps I need to try it again and reassess its crappyness UD

Thanks Fabio for the reply. I opened my PDF copy of the 464 manual and found the +15 volt end of the wire on the TRIG-VIEW switch but didn't know where it went from there. Did some careful perusing of the TRIG-GENERATOR SWEEP BOARD and found it at the bottom as you descibed it so then after I got my early 466 manual searched it out and found it also.
Appreciate the description of the circuit and also the chip diffs
i have started to put together the list of capacitors I am going to need and have pulled the 6 caps from the interface board for the 466 I did not have any real problem getting them off was a bit hesitant at first because of the horror stories on here from folks doing that. Some time back I picked up a real nice desoldering tool from Radio Shack it is a bulb sucker type with the bulb attached above the handle and to the tip with a tube so you can put the tip on the connection to be unsoldered and when soft just release the bulb cleans off and out all the solder.
Once I got the first one out it was easy to see how they were attached just put the tip hole down over the small pins first sucked out the solder so they were loose the worked on the big one wiggling the cap while heating took two three time to get it loose big hole filled up with solder on that one.
Have a question on two of the tant caps used in the power supply for one section of the output they are two 47uf 25v caps # 1712 & 1713 they are in a half wave rectified section and across the output for the +140v supply it seems that 25v is a bit low here? Any comments here?
