Picked up a working, but tired sounding, unit late last week. I plan to refurbish it and wanted to share the project with the CAM community.

Unit shows no signs of any repair or modification. Just how I like it. :-)
Radio buttons are a bit intermittent but come in fine with a bit of exercise.
Tuning shaft needs some lubrication on the bearing surface, as it squeaks a bit.
Opened it up and pulled each card to inspect and make a list of electrolytic capacitors to replace. (about 50 in total).
Just pulling and reseating the cards improved indicated signal strength!

Project will take a couple months but I'll keep the thread updated best I can.

There are 5 electrolytic capacitors (3x tantalum type) that are directly in on the audio path of the T-100 and another pair are used for AC bypassing. The rest of the audio coupling capacitors are plastic film type likely mylar/polyester. I suggest you limit yourself to these capacitors first unless you have access to a proper FM stereo alignment gear.

I haven't scrutinized were the electrolytics are in the circuit but at a glance, the capacitors used in any of the radio stages are likely ceramic, and I won't be touching them.

ej251 eh?
I have a vanity plate that i'll soon mount on my 98 outback. (not an ordinary 98 outback :-D )

Yup Subaru EJ251 engine with AWD. Good catch!. I have since new an '04 Forester 2.5X AT now with 247,000kms and NO leaking head gasket.

This is the first T-100 i've ever heard.
So far my modified KT-7500 sounds better (at a fraction of the T-100's price) but does not perform as well with the difficult stations.
I'll reevaluate after the replacing the electrolytics.

Love the Scoobies!
I did a turbo swap and lift, on my winter wagon.
Rebuilt 2.2l turbo from 94 Legacy Sport. Wisco pistons, ACL bearings and STI timing belt tensioner.
Then rebuilt and modified the original heads from the 98 and bolted them (and the 98 intake manifold) to the turbo block.
Stock computer now manages the franken-turbo engine. Passes emissions no problem.
Real sleeper. :-)

Bill,

Great pics! Hidden under the hood is a turbo engine. Without the hood scoop of the Scooby who would know?

My Fozzie is stock and for some reasons it feels under-powered from the get go. I do my own car maintenance but haven't figured out what is causing it to be missing the full 165HP. The heads on mine were taken out under warranty around the first year due to a pinging complaint. My guess is that they put the WRX/STI gaskets while putting everything back together that is why mine doesn't have the dreaded head gasket leak after more than 13 years.

So much HP is the EJ22T the way you are running it?

I had the FM-only T-101 with the rare factory walnut cabinet for 20 years. I sold it in '07 and I regret it to this day. Big mistake.

...faulty knock sensor, the wrench that did the head gaskets didn't time the engine correctly, bad o2 sensor.
Could be a few things.
