Yup. They are also LME49710, and pre-mounted. Time to update the description.

And single power placid uses 8pin DIP LME49710 now?

BrianDonegan · 17th October 2010, 11:43 AM

No, both single and bp use soic.

Nope, sorry.

No problem, I have a steady hand

Just wondering why you switched from opa227 to LME49710?

BrianDonegan · 17th October 2010, 01:13 PM

Both will work fine. The LME is lower noise and I had a ton of them on hand.

Sorry for stupid question, but can i drive Technics sl1200 from LCBPS (maybe parallel). Technics needs 21 volts inside and around 0.8A max. Or could placid do the job?

my 3 Placid BP came with VR1 and 2 at 20ohm , that is iaw the part-list, but not iaw schematics and setup procedure to set it at aprox 50 ohm before powering.

have i missed something here?

We will need to update the manual. 20R is correct, just adjust it to the max resistance. remember that they have a tolerance, so if it tops out at say 18R or 22R its all fine.
