Jer's PLWO to be... (Jer vs the 700, Round 2... it's "Personal" this time)

Q4 does not need to be matched. take one out of the loaner.

 

[laatsch55]

For Q4, the MPSA92 IS the only one specified.

 

[laatsch55]

Excuse me, MPSA93 isd what we've always used, now Joe is specing the MPSA92.

 

[Gepetto]

MPSA93 will work fine. I have moved to the MPSA92 because it has a higher working voltage, thus better margin, higher reliability, better quality. I have been migrating to "better" where ever possible in the White Oak kits. Use ON Semi or Moto if you can find one, best quality.

Just an illustration of a guy who'll give his right arm (and tranny, to boot) to help out a friend!

Thanks Lee.. should I put a piece of tape over the pwr switch with big skull n xbones to remind ya when you get it back?

 

[jbeckva]

Houston, we have liftoff again...

The world is the world is

Love and Life are deep

Maybe as his skies.. are wiiiiide!!!

(sorry, ahem.. singing along.. heheh.. )

 

[jbeckva]

And, there's the finished result. Whew.. who's got another one "needing it"??

 

[laatsch55]

Excellent Jer!!

 

[jbeckva]

Lee want me to get a few of those MPS's on order and fix yer loaner before sending it back? Not a prob

Hmm.. speaking of which, I haven't seen hide or hair of the cabbage case yet.. where that be-at?

 

[laatsch55]

On it's way to Oklahoma. The Guinea Pig is living life as a loaner. The Ken Nelson was reluctant to send his 400 for the White Pak treatment so I said it only took 10.00 to ship the case with an amp in it, so a new tradition was born. We'll not ONLY FIX IT< WE"LL GIVE YA LOANER!!!!!!!!!

 

[jbeckva]

LOL.. Well, I have time to get some MPS's on order and have your 700B back up to snuff then!

So.. the last "lesson learned" FYI / FWIW... Put that daggone DCP in "right".. If you have to get some parts for it, get 'em.

ALSO... On a tip from Joe, I swapped back in the OLD twin-10 ohm resistors on the Zoble for the one that comes with the DCP - the one that comes with is a wirewound, which could put some inductance where you don't want it to be. I'd take some pics of that, but hey... it's buttoned up for now! (basically I stood both "on end", then ran a small lead wire down to the other solder pad).

Sounds good.. better than it has ever so far!

 

[laatsch55]

Hmmm..... wondered about that myself. Those square lookin porcelin things??

 

[jbeckva]

Yep

 

[laatsch55]

hOOKAY, OUT THEY COME....

 

[jbeckva]

Well hmmm... that sucks....

Looks like the noise I was getting (a good half a volt AC, at that) seems to have originated from the DCP. Guess I need to pull it and see what's broke, eh? The AC must be bleeding through somehow over to the speaker outputs.

 

[jbeckva]

Got it out and checked it over. Nothing "obvious" I can see .... hmmmmm! I wonder if a wire came loose?

I'll have to put 'er all back together and see. Tomorrow tho.. it's getting late.

 

[laatsch55]

Check the 6517's. That's why I sent you some.....they can be wounded, take my word for that one!!

 

[jbeckva]

Yeah I remember you were saying something about the DCP and it causing noise.. where's that thread at?

You sent me some??? I must be dense.. when??

 

[jbeckva]

Hmmm.. but I do have quite a few 2n3439's. Might be overkill, but they are 450V devices. Trick would be mountin' em... hmmmm
