phase linear 400

tomorrow....i am pretty stressed....
however, can the amp be operated without the emitter resistors and r1 and r3....
i will make sure i can adjust the bias tomorrow....and order the transistors and whatever else you people think i need....
my new to me 77iv is shipped....
i will give the chinese one to someone i dont like...
i sure would like a recommendation on a decent analog meter....
i do like them too...

Hell man, if Joe, who designed the boards can't fix em, nobody can.

But, I'll agree, Joe gets a BIG pat on the back. If it weren't for Joe, we'd all be listening to Phillips transistor radios and Sanka boom boxes. Thanks Joe, we all appreciate your inventions and gin jobs

Gene. Don't forget extra fuses. This is the 77/BN I bought used. The big fuse was blown. Download your owners manual and the fuse specs and part#s will be there.

yes sir!!!
thanks!!!
lloking forward!!

 

[gene french]

looking forward!!!

well, mr. joe certainly understands the boards....
i removed the two transistors, cutting them out and cleaning board, as instructed....
hooked up the two diodes....and guess what...
i have bias on left channel...was exactly as i set it when i removed the diodes...365mv
i dont understand what was wrong....the transistors tested good....but, evidently they are not....
maybe its the chinese meter....or my chinese brain....
anyway....i guess i will clean the back plane of the bad resistors ???
i dont think it will produce music with the bad resistors???

good morning phoenix....

 

[gene french]

got my stuff ordered..i feel confident that we have found all bad components...one of the emitter resistors was burnt on the back side..saw it when i removed the bad ones...

Diligently working on your PL 1000-II

And agree on getting spare fuses ... before you need them. When I bought mine several years ago, Allied Electronics (yup ... that old company) was able to fulfill with great prices. The fuses have gotten pricey, so best to be careful!

I must be doing something wrong. I have never blown a fuse in either of my Flukes in over 20 years....................

i downloaded the manual...and a drawing of the fuses...with a fluke part number...i will open it before i order spares...it does not look like yours!!!

Knock wood!

I never needed them either, but just in case ...

Just in case??? If I had spares for everything for the "Just In Case", I'd need 10 warehouses.

 

[J!m]

And a spare warehouse- just in case.

let me borrow it for a few days...lol

george,
took your advice...
ordered the dsp from dayton audio...lots of sugar for a nickel...parametric eq...active xover...mixer...4x8...
and blue tooth module....has phone app and pc software...
plus connectors....i smell a rewire headed my way...maybe this week my other parts will trickle in..

 

[George S.]

Gene is going to bi-amp and tri-amp. Gonna build a WALL OF SOUND! Don't need a 700 when you have many 400s.

i saw a mod for the on click somewhere...my old 4 fin does that upon power up...the wopl and 8 fin no...i think some one sent to you...was a resistor i think...
