My venerable Foreplay has been working well.. for years.
But recently has developed a hisss (with no music playing).
Could be aging tubes, but the current ones JJ's (my fave ones) have 'maybe' 24 hours run time on them.
Venerable 4play has ..ALL.. the mods except for the "snubber' Because (oddly) it Never actually needed that one (no hisss or at least barely audible ) .. until now.
What is the technique (circuit?) for adding a wall wart Heater power to the tubes.. I have a 12v 2 amp unit handy.
Also... What is the downside to removing the heater duty /load from the wee Transformer?
Will this Up the available Volts to the rest of the Gizmo?? and if So.. How do I mitigate that??
Sorry for all the questions but my carefully hoarded info disapeared with a Hard drive fail.. sigh.
thanks
