[Hallicrafters] Attention: SX-88 guru's

[caladonia at juno.com]

The top slug of T5 of my SX-88 run2, has the same type of slot as the
bottom one. 

Thanks for the tip on the micas, they don't seem to be leaky, but I
will be replacing them while I have the subchassis still off. Yes, it
certainly is fun!

I'm in the process of restoring an SX-88 ... great fun.

Wwhen attempting to make the 2125khz and 1500Khz crystal activity 
adjustments (top and bottom slugs of T5 on the 50Khz IF subchassis) I
noted 
that the top slug of T5 didn't have an adjusting slot ... looking down
into 
T5 only showed a smooth top of a slug. Interesting!

Maybe the slug was broken?
Maybe there was some sort of production change in which there is only one 
adjustment?
(Messing with the bottom slug (2125Khz xtal) does affect the 1500Khz 
adjustment as well)

Does anyone have any comments on this? I have removed the subchassis for 
capacitor replacements (and by the way, if anyone does this be sure and 
replace the 4 390pf mica caps as well as the black beauties - the micas
see 
plate voltage on one side and in my receiver 3 of the four were very 
leaky!) and before I reinstall it I want to determine if I need to mess 
with T5.

Now, just in case, does anyone happen to have a T5 (or slugs) laying
around?
I would pay a king's ransom.  Hi.

Thanks in advance!

73, Bob
