A little off topic I know but....

I have just been given a Phase Linear PL700 to repair by my mate. This is rated at ~750 watt per channel into 4 ohm.

I reckon that would drive your speakers Brent!

I received my heatsink components late yesterday. I have mounted the main part into my test amp and have rested the veins up against it.

So this should give some idea of the final look.

Lookin' good mate, I'm sure you did rest your blue veins up against it

Morning Brent,

I was looking at the schematics of the 66 and the 6010 which are practically identical.

The 6010 lists the input cap as 220uF but the 66 as 22uF.

Looking at the impedances involved 220uF look awfully large.

What is used? If it IS 220uF why do you think it's so big?

Even 22uF is a bit on the big side. My old Rotel had 1uF film.

Confused... unless I looked at the wrong part.

Its actually 220uF on the 66 too. Lots of errors on the sch, but when you look at the parts list its right. They corrected them mistakes on the 6010 sch.

I swapped mine for the BG AC 50V 10uF. I picked 10uF as the output caps in the cd are BG AC 6.8uF.

Ah... the reason I was asking is I have some BG N 10uF/50V lying around (new and unused) and thought they would be good here.

Pop em in and test. Should be ok.
Give it a few hours to settle
