When it rains, it pours...at least it does in Florida.
Seems that Q8, an MPSH10 transistor did not make it into the parts list (has been corrected in the Docs)
Hence, it did not make it into some kits.
Q8 is part of the AGC system...not a frequency sensitive parts.
If you are missing Q8, it can be replaced with almost any NPN transistor like a 2N3904 (used in 1Watters).
I can not ship a MPSH10 transistor in an envelope, only in a box with a ship cost of almost $5
If you have an NPN transistor in your junque box for Q8 I would appreciate it.? Note the difference in BASE & EMITTER config.
If you don't, I will ship you a MPSH10.
I think this is my last kit.

Sometimes you only have say a yellow T37-6 vs a red T37-2. Can it be used? Yes but you have to adjust the # of turns and then you also have to judge if the new number of turns will fit on the toroid. I found the attached information very useful.

When I enter T68-7 and 60 turns, the mini Ring Core Calculator show 18.7uH.? It also says the max wire size is 25 gage.? So, 26ga would be tight, anything smaller would be good unless too much current will be used.

Thanks Chuck!
I was hoping you would change your mind and do a series on the new 5Watter by Diz.
I like how they match your revised build guide - 5w.pdf (v0.95)
Now I feel better about proceeding with my own 5Watter build plans.

I just bought 3 rolls of magnet wire on Amazon. 26, 28, and 30.
It did not cost much.

The wire size of a toroid affects its inductance and Q. Those effects
are small and the values in most circuits aren't sufficiently critical
for them to matter. The toroid cores are not precision components, and

Gang,
Last weekend I bit the bullet and ordered another 5W20 from
Diz, W8DIZ, at KitsAndParts.com for two reasons. I ordered
it during the weekend and Nancy and Diz shipped it out on
Monday and I got it Thursday.? Started Friday (yesterday)
building and doing the videos.
The first was to build a stock kit and not a 5W that I had
the board made at JLCPCB and used parts from my own stock.
Secondly, I thought I had better build a board and at the
same time do a series of videos showing the test points
in the manual at and to also
force me to double check for typos and maybe find a better
way to do some stuff.
Thirdly, to do an experiment, which I will reveal later
this upcoming week, if it works out.
Yes, I went from two to three to see if you are paying
attention.? :-)
First of the videos is at
and I have done 3 and going to the lab to do #4.
FYI

Re: 'Alfa-Bravo-Charlie' = Old? Obsolete?
Doug,
You are right, but I just came in from the lab and
this thread is hereby terminated.
Everyone that posts the continuation of this silly
thread will be moderated for a year.? This will
significantly slow down the offending individuals
posts if not terminate them.
Back to technical subjects please.
