There is a little more information on the 32 and 37 at: HT-32 | WD0GOF<https://wd0gof.com/hallicrafters-radio/technical-discussions/ht/ht-32/> Walt Cates, WD0GOF https://wd0gof.com/Hallicrafters A

if it drifts still after 6 hrs i would look for a bad mica cap in the vfo also. 73 Tony wa4jqs Anthony W.(Tony) DePrato WA4JQS Extra Since 1962 CQ DX HALL OF FAME #35 HONOR ROLL CW RTTY PHONE #1 MOST

No, I have not checked that. I will check it when I pull it apart.? Adding it to my list! Even after its been on for maybe 6 or more hours it still drifts.

i had the SX 101A version and never had any drift problems the 101 may have been different but can not recall hearing it was a problem. did you check the heater resister ? it is across the AC line and

The plate voltage series resistor is? of course a really good way to measure idling (or any) plate current.? And the best way to set the bias voltage. But be VERY CAREFUL.? When you're using a

Good Stuff, thanks very much! wa3gin [email protected]> wrote:

That is the test point used to set the bias (PA idle current). See section 4-10 of the factory manual. For a helpful mod for adjusting idle current see: ht32-37-plat-i-mon-mod.pdf

My 101 drifts, and from what I read is a common problem.? I see several possible cures for it. 1) VFO because it has a *drift* correction adjustment that is simple to manipulate. This from a post on

My 32A has a test point located near the 6AB4 tube in the front of the chassis.? What does it test? Thanks-George KN3PAT

It's looking pretty good!? 2800V should easily get you about 600W or more? if it doesn't drop too much under load! Running 3KV through an octal plug is very scary though!? You might want to

Hi Bob, You've got it well down the road at this point. It really looks like a nice example from what, 60 yrs ago or so? Can't be too many that are in better shape than that. While the Jones connector

Hi John. That's the factory supply and original transformer. It came with fins! You can see them in the manual photos. Somewhere along the line, the 866As were replaced by a pair of solid state

Looks great. Did you add the heat sinks to the transformer? It's a nice job. Nice looking amp! John [email protected]> wrote:

HI, I think this is the 2nd time I've emailed you on subject. Still waiting to hear the cost. I can't commit without knowing the total cost including delivery. Thanks for doing this, dave wa3gin

Please email me if you want a panel. They are done and ready to ship.? Clark at Clark Turner Tuning? Or use QRZ C

Richard, Thanks for the information, just what I needed to know. John WD5ENU [email protected]> wrote:

The speaker field can be replaced with a 1500 ohm, 10 Watt wire wound resistor. See the schematic for the S-40 or S-40A for details. I am not sure what the plate load for the transformer should be but

I know I have asked about this before, but lost the return email. I have an 8 Ohm 5 inch 20 watt speaker and an audio transformer, primary is 500, 1500, 2000, and 3000 Ohms. Secondary is 4,8,and 16
