Thanks Nomad, this issue had me flummoxed for a bit. This morning I got the scope working to extent it passed the manual's section of "Test & Adjustment". Everything seems to be working fine. Dr Frankenstein, thanks again for the Assembly manual.

I think I made a mistake via my misunderstanding of Metering. I may have figured it out but I’m looking for corroboration. The Heathkit build instructions have 3 measurements of Resistance that should be attained prior to applying power for the first time. My first measurement was far too low...

That Assembly Manual really helping. I'm going step by step to verify all connections. Initial attempt to perform pre-power test measurements failed 1st step: Measure resistance btwn Ground & lug/pin 1 of V6 (Rectifier tube plate, IV2). It's lower than it should be by MO's (should be approx...

AND ....... That QST article is the bomb! Circuit upgrades for a 60 year old device. This forum has unbelievable depth in it's Human resources. Thanks again. neil, n2eye

Dr. Frankenstein, That manual is exactly what I needed. A huge thank you for the Assembly document. I looked everywhere and could not find it. I've been using pics which relies on orig builder and often fails to capture what I need a day or 2 later. Trying to stay away from the two, one-piece...

Nearly a Month later, got the new parts installed into scope but have not yet applied power. I planned on replacing every resistor pair (same value) only. After I measured a few, it was obvious they all need replacing. They all show far higher resistance than their color band values (like...

mea culpa, Got my parts today (all of them) despite the July shipping date on first invoice. I don’t understand the why and how of it all but I’m satisfied with my order. Now it’s time to refresh this old Heathkit scope

:rolleyes:

OK, I put in a request for clarification. I also searched generally online and saw I was not the only person w/shipping issues. Thanks for the feedback

Past few years, when I need several different parts, I've been ordering from Newark Electronics. My last order was a week ago, mostly caps and a few resistors, $60 total. Everything I ordered was marked "in Stock". A few days later I'm notified my order will not ship until July 15. :oops...

Got this from eBay a weeks or 2 ago. Ordered new caps and some select resistors. Input adjustable rear panel from 1/2w to 1kw (SSB I presume) just a jumper with a signal tap to scope inputs. It's old but limited features so it's not so complicated I'd avoid using it. Will it have "use...

Same Cap! "it does serve to improve feed-line balance and reduce the potential for feed-line radiation. Most coax systems are already referenced to ground via chassis ground or shield grounding at the point where the coax enters the shack. It is a design form which is only important in terms of...

It's just 2 more caps? Yet, they are inverse-synched to the primary 2 sections. My small brain couldn't grasp the use of such an piece. Was considering it to replace my Load cap and remove the extra hardware. (1 I have now is too narrow range) but could not find specs for a Johnson 169-25. Do...

I saw this on eBay Seller wrote it came from a Viking Matchbox Tuner. neil, NYC

saw title thought it was a joke

Mystery solved over Normally Closed vs Normally Open. The Part marking convention is denoted by whether the terminals are Bent/Straight and by the color of the insulator: Bent foot w/ white insulator is Normally Open. Straight foot w/ black insulator Normally Closed. My problem was that the...

I don’t have as much electronics equip & tools as most Members but, it’s a lot. So when the relatively new Garment Steamer stops working, it looks funny if I can’t fix it. I need a thermal switch & all I need do is find one. Illegible Part # no help from Pur. So I try AI for the 2nd time...

1st opportunity to try desoldering station (Yihua 948). I had a Lasko 42" tower fan < 1 year old that stopped spinning. I used the Yihua on one of the thru-hole PCB’s that needed attention. Have not cleaned the filter spring yet but nozzle sucked-up some big molten globs and cleared the pcb...

I’m saddened to read your plan to abandon the 201. I was watching and hoping to see it work. I had one w/the same goal that got the better of me around 2010. I still have the outer case/cage-type that the chassis slides into for anyone (free) to pick-up (Bronx). My letting-go was...
