Nothing wrong with my Beyers, I have only one set but I like them, ET-1000 Admittedly they're not your standard run of the mill Beyer.
Then again, I like the Koss ESP-9 too
Heh, I meant how did you know the MOSFETs were probably shorted. I suspect dark powers are involved
looks like R8 is only reading half what it should be too and the smaller transistors all seem to be in the 0.67 V area.
Thanks again for the help AMB
Yeah, I was just looking at the order page. I'm just going to run my meter over a few more resistors etc to see if I should get anything else.
R4 and R5 are measuring 55 Ohm, R6 and R7 are measuring 100 Ohm. Two more things for the order.
How do you do that?
It appears both MOSFETS on that side are blown too. Is there anything else I should check before ordering more parts. Can I buy those from you?
Ok, It has a near perfect 30V AC going in but totally screwed V DC numbers coming out.
I officially have no idea what's wrong with it or how to fix the high output voltages or fix the voltage imbalance. I'll see if I can find another S22 to buy. This is above my level of DIY.
well it was just the power fuze when I connected a board. Replace the fuze and it's fine again.
Now worried about connecting the boards again. I'll try a different board
I finally got the resistors, replaced the broken pair and now I'm reading +39/-37 V DC on each of the three pads. Any Idea why the reading would be so high. I'm getting 30V AC in.
Beware.. those razors are pure evil Colin.
I think I must have removed enough of my face over time to give someone a decent sized skin graft due to that thing. It was my first razor in '75
