Thanks to Chuck S. I got the service literature for the 90 yesterday. Today, I finished the recap and changed all out of tolerance resistors, save one, a 240K ~3 watt. I don't have any of those in my current inventory. I found some doozies, too. Out of the three 240K resistors in the audio circuit, two were well over 700K, one was virtually open. The two 490K resistors in the detector circuit were both well over 4M!

Glad to help Brenda. S-l-o-w mail it seems.

Don't for get to re-stuff that tone control. Looks original in the photo.

Well that's why I started the Recarb and Recap School of Everlasting Rejuvination. Few followers so far.

This is the same tone control (or similar) we have in 18.
Not only it has rubber wires, which cracked, so I had to splice them, it is also potted.
I actually left it alone. Did not have it in me. This is one single thing in the whole 18 that I did not restuff.

The higher the value the higher they drift!!!

ps WHAT CUTE LITTLE RESISTORS YOU HAVE THERE!!!

[BrendaAnnD]

All flameproof, all the same or higher power rating than the originals.

[morzh]

It is amazing but today's 1W resistor is about 1/4 size of then 1W resistor.
What bad is that sometimes the leads are not long enough to span the old resistor and so the old one gets cut and then the new one gets soldered to them.

[BrendaAnnD]

Yes, it would be nice if the powers that be would lengthen the leads about an inch. It's not like it would make a substantial difference in their profit margins.

[morzh]

It could. It's copper. Copper. Copper is expensive. I am sure one lead of a power through-hole resistor is worth more than a whole 1206 SMT chip resistor.

Hi All;
Brenda Ann, You could use an 1206 SMT and make the leads as Long as You like.. Soldering a lead to each side of the unit..
THANK YOU Marty
