Old, untouched, unmolested.

Such good condition think I'll set the bias and offset and let her rip to see how it sounds stock. Anyone have the service manual?

Found it on Hifi Engine

Watch those chassis cover screws.

I would strip the boards like i showed in my fixit posts...
Are the inputs opposite of the outputs?

 

[Gibsonian]

Eventually I will. This un like zero dc offset barely had to adjust the bias. Gonna listen like 1982 for a bit

Those were the worst offenders on the board , fuckin bias adjusters....Ohhhhhhhhhh..... they definately got trashed...

It sure cleaned up the tweets on the tri-amp....

Same issue here but only deformation of cans, no puncture. I loosened clamps and slid the caps 1/8” just to miss screws.

Lee left and right are left and right. Stock amp sounds very good

 

[laatsch55]

They usually did....my ol bud in Phoenix had a 300 on the topside of his 4.5's.....and a big Bryston on the bottom. The 300 sounded really good....

Mine will run the tweeters in the triamp setup. I think it might be better stock than current amp in there, a Yamaha MX1000

A superb tweeter amp for a big active crossover system. Best I can describe it's output is fast, accurate, and clean.
Works extremely well with WOPL's.
I like the lack of meters and how it matches the other Series 2 components.

Will be cool to have the 700 (full WOPL) on the woofs, 400 (full WOPL) on the mids and 300 on the tweets. Full on Phase and White Oak setup. One day the big Model One. I only listened full range when I tried the 300 on another system. But the highs seemed quite good.

 

[laatsch55]

I can vouch for that...damn good..

 

[Gibsonian]

Set bias added little lil bypass caps and she’s running highs. For sure improvent over the MX1000. Living in WOPL Phase Nation here

I’ve never seen a 300 series two before. Had to zoom in to see what it was.
