Hi Lee, if I knew you needed the cap clamps, I would have sent you a brand new pair with the order I shipped out today.

Sick world we live in...

As they say George, Oh Well... :-)

Totally different Jim. MOSFET have a positive tempco D-S unlike bipolars that have a negative tempco B-E. You can directly parallel MOSFETs and they will self balance as long as you have gate damping resistors to eliminate parasitic oscillations between the devices sharing the load.

Probably MOSFET tho...

If I knew the dimensions, I could likely 3D print them for you George...

Does no harm either way, they are only essential in columns 2 and 4 as you correctly note.

Don is correct. Matching is unnecessary and does nothing. The local negative feedback provided by the 0.33 ohm emitter resistors forces sharing across all the devices and prevents thermal runaway that results if you do not have these resistors. If you purchase devices from White Oak Audio...

Yes, BUT ONLY AT THAT RCA JACK INPUT POINT. It shunts any possible external ground loops by virtue of that.

Short answer, no. Just insure that you also add a very short jumper connection between the shells (ground connection) of the 2 RCAs as they enter the chassis. That is the function that the copper plate served.

Lee the input on the control board is direct coupled. It is recommended that you direct couple the RCAs into the input of the control board. Any decent preamp has a large coupling cap on the output. For reference, every PL400 ever built was direct coupled and came from the PL factory that way.

That is not factory Lee...some prior owner kludged that in there...

You mean even more Alex ? :-)

Holy cow! I had no idea my Mark II deck was worth that much...

I will get there Lee. I play catchup over the weekend...

Or better yet, replace the chassis as put in the backplanes to get full comp operation.

Depends on how the 2 -95s and 2 -96s failed Gene. Please advise on each device what you measured from C-E, short or open. One device failure can start the chain of events that occurred OR the failure on the DCP could have started the chain of events (not sure why the detection IC would pop...

It does no harm but is not necessary either...

Leave them as is. No need to raise any component on White Oak Audio boards.
