Stephens Phase Linear 400--In for the works.

[laatsch55]

Silly man I am I've had the 15hz cutoff filter on the Spec 1 IN for going on 15 years thinking that was probably the bottom end, uh//////////........NOT SO JOHHNY!!!!!!!!!!! Took the filter out and aw jeez.....

15 hour day today folks, I'm toast....

Stephen had one last request, a 12 gauge power cord. Now that ,that is done , she is buttoned up with Joe's Rev"B" light board and her she is........,



In the last 24 hour torture test, She gets shipped Thursday Morning...


Nice amp...

Great looking amp Lee. Nice work.

Great looking amp Lee. Nice work.

A plus one here! 12 gauge power cable - talk about a stiffy.

Neat as a pin. Wish it was shipping to SE Iowa.

Thanks Guys, I liked the way it turned out too.

Beautiful job, Lee...over 300 RMS/channel at 8 ohms? Out of curiosity, two questions...

1.) What is the rail voltage?

2.) Is there a difference in output power between Quasi Complimentary and Full Complimentary configuration?

 

[laatsch55]

The 315 is suspect. Will retest before I ship it today, one of the rotary switches in my BPI loadcell (the same one used in the PL factory engineering dept) has some dropouts. Rail voltage is 82.3 I think that 315 was with one channel driven...

 

[laatsch55]

The FC optionb is probably good for 10-15 watts.

 

[laatsch55]

I figure 1% distortion as the onset of clipping. So I'l run a THD & N sweep on the AP then hold the input figure as I change ovr to the LEVEL function and ee what we have. At leat it's consistent.

292, 293 wpc into 8 both loaded and driven

Mighty impressive Lee, are you going to try a 4ohm load and see what it tops out at?

 

[laatsch55]

Not on this particular amp. I don't have time to fix it, IT HAS TO BE SHIPPED TODAY, if it's going to make it's own debut on Steves music party day.

When I get The Pig back and FC him we'll do it. The Pigs used to blowing up.

Don't know if anyone else has installed the Rev "B" light board yet, but man what an improvement!!! A lot faster meter response.

 

[laatsch55]

The Pig has some healthy rail voltage. I do have the worlds hottest 400 tranny here though. Came out of an early 400 when Bob's brother was still winding the tranny's it's measured at 108.6+/-

How did it get the name "the pig"?

I am confused Lee, a light board makes the meters react faster? I thought it was just for illumination purposes???

A pretty good read..

The PL light boards also contained the meter drives. And this is Joe's latest LED light board release, nere's the release notes.....
