Decoding Bakelite tarboats question - wu8v - 02-10-2010

I have started to read through all I could, and ordered the info for my radio (37-9) from Chuck (schematics and such) and read through the article describing how to rebuild those tarboats, and I am foaming at the mouth to get started.

Sooo, I thought that I would get started on developing a part list that I need to replace the caps.

Stumbling block (no pun intended) on the very first one that I looked up. (part 44) it gives a part number of 6287 DG for a dual .15mF cap. (tarboat)

So I go to the trusty part list fully expecting to see a 6287-DG.... No joy.

I am assuming that there is a D component, and a G component to the 6287, but houses have been burned down for assumptions.

Can someone tell me exactly what is going on with this part number, and I will extrapolate from there for the others, I hope.

Thanks so much,
Kurt

Hi Kurt

Go back to Chuck's page on rebuilding bakelite block condensers.

http://www.philcorepairbench.com/bblokcap.htm
Scroll down to "Universal Type 6287."

Look at the specs for part no. 6287-ODG - this is equivalent to 6287-DG.

Anytime you have a part number like this that you cannot find (i.e. 4989-DU) that you cannot find, add a letter "O" (as in 4989-ODU) and you should find the specs there.

If not, Chuck's page also directs you to the book "Philco Condensers and More," 2nd edition. The page gives ordering information for this book, which is a big help to anyone who works on Philco sets on a regular basis.
