Okay any last-minute advice?

I opened it up and it looks like the transformer wires ends are wrapped around and soldered to the wires that I am replacing then crimped for before leading out.

I'm going to put a small shim behind the connection and desolder with copper wick and then reverse engineer it back with the new lead.

I know color wires really don't matter but I puchace them when I was in a greener state and would like to use them. I have 600 volt wire and then the 200 wire I would like to use the 200 volt wire because it's thinner and easier to bend around. In the schematics it states the colored wires that lead out of the output transformer so I was just going to follow that as shown in the photo.

Thank you,

So if I could go back in time the biggest advice or hint that I could offer everyone is to listen to the sound advice given at the beginning of this thread.

For now I am on my own endeavor to gain experience in this setting and work myself out of what I got myself into.

With that said, will close out this thread out with a hearty thank you and will finish this up in the post that I should be at. I will be linking you all to it of course.


Thank you

Hello Greg,
sounds like this set has taught you some new ways?

After 40 plus years of working around electronics stuff like this is great because next time it will become a little easier.

Sincerely Rich

Just remember that the ends of the primary winding (connected to the tube plates) have to withstand almost twice the B+ voltage under normal conditions and a lot more under abnormal conditions (like if the speaker becomes disconnected).

Thank you for the send off, gentlemen! I will miss my time at Hints & Kinks but I must now travel that lonely road to put the knowledge gained here to the test.

I will look further at the 600 volt wire as I wait for my mylar transformer tape to show but it is so thick...

Best regards,

I am sorry, I misspoke in the other post. The small profile cloth covered wire that I have is 300 volt rating 20 gauge it is Radio Daze wire. So 300v not 200.

I wish they made a small profile 600 volt cloth covered wire but I think we all have been down that road before as I notice in the other threads do I will not start it again.

Update.
I just ordered another full spectrum batch of 20 gauge stranded 600 volt cloth covered wire from Antique Electronic Supply. My gut tells me there will be no difference in thickness but I had to find out before moving on.

And when this batch arrives I'm going to supply measurements of all three sets of wires with notes and photos just in case I'm not the only one looking for the grail.

Thank you,
