Gibsonian's Cherry Pl 700 Ser I, soon to be a PLWO-1000

Got the "Thermal Evented" sockets out. All emitter resistors out, time to go back together with it.....

Blackened sockets is usually a sign of things that went wrong. I am so happy that you are breathing life back into that 700B.

Series I , and the 1N4007 diode that went put the new hue to em!
 
Correction, 1N4004's... Left channel positive rail done..., new sockets in...

Right channel plus and minus rails done. Going to redo the hookup wire from the board to the back wall. With the silver wire provided by NavLinear, (thanks Dennis)

I'm glad the wire is working out. You can get spoiled using interconnect wire that has good insulation characteristics. I need to shoot you out some shielded single conductor wire - next goody box. I'll see if I can include some solder sleeving - cool stuff.

I'm listening to another Shpongel Remix - takes you to another tangent of the music world. Thanks for turning me on to these guys! I have a CD on the way from Twisted Records - another Shpongel CD that I don't have. The Remix is MP3 but so far it sounds good and goes in some different unexpected directions but I like it. If you're interested I'll burn a CD and shoot it your way. I'd like to get Ed's faceplate holder out soon - I have one made in ABS (black) that should handle the 700's but I want to get one more done using PC.
 
Everything ent fine on initial power up EXCEPT Low bias voltage on the right channel. What ever took out the diode on the back wall probably took out the bias tranny, got some weird readings on it.

Yep, that was it. Replaced the right bias tranny, we now have 380 mv bias . Time for Cathy to be tested.

Yes - that's the white material. I believe that next week I'll get some machine to make a few goodies. Between some down time due to the machine breaking and all the work we had stacked up I have not had any time to get fun stuff done.
 
Alright then Lee, what did AP have to say about all this. She has the biggest say of all in this.
 
THD & N I've seen better and worse. This is with the 15024's. Quick time out to swap in the RCA 410's


Dennis the AP are more than just cool As THD & N said " They Are The Shit!!"

I know - just jealous.

The HP 8903A has some good points but I'd sure like to either run it remotely via a GPIB buss or get an X-Y high speed plotter. Much easier than taking a butt ton of measurements but why am I complaining anyways?
 
Yep - no beer here for a couple of weeks but just pounded a couple of beers at the barn!
