cs4 voltage problem

Did you also maybe swap a 47K input resistor for a 470K output resistor on one channel?
 
wow measuring 55 ohms across input RCA with 47k ohm and red wire disconnected form tag board to ground.  Does nylon washers go to junction of heater noise caps?
 
Post is unclear - do you mean the RCA jack measures 55 ohms all by itself? In that case you probably have a solder blob or wire whisker partially shorting the jack.
 
John,

All 4 RCA Jacks have nylon washers that "Float" the outer conductor, signal common, from the chassis.  The signal common and shield are taken to ground elsewhere.

I hope this is what your question was about.
 
Hi all,
Here are the results so far.  The amp has no intermittancies when I tap on the circuit boards or sockets.  However the gain at 1000 hz is Left chan 42.85 db and Right chan. 49.33 db.  What components set the gain for the circuit.  Any suggestions greatly appreicated.

Many thank again

A good idea would be to swap EF86's to see if it follows a tube.  6922's can also account for some imbalance, but 7dB is pretty large.


In the Eros, the 75K plate load resistors are (in my opinion), most responsible for gain.  Next up would be the EQ (if you have a connection issue within the EQ, it can present as gain imbalance), and lastly the tubes themselves.
