Rookie question

Suppose you have your CJ or any other equipment for that matter.... all broken-in (in my case the CA200) and you rotate your equipment around every few months or so...does it have to be broken-in again after a 3-4 month hiatus?

in such cases usually 50 to 100 hours of break in is enough.

Thanks ronenash......no wonder my Mc sounded so lifeless last night after the rotation.

Yes, I've found this to be case as well....gear not in use for a time needs some re-running in, but generally a few weeks is sufficient.

Hmm...I better put the Premier 17 and LP70S back into the system! ;-)

I rotate power amp once or twice a week and do not find this a problem. Its only when you are not using your gear for a few weeks that you will need reburning it.

I would expect that if its store for a year or so you will need a considerably longer burn in.

In addition to gear breaking in again , the dialectric surrounding interconnects and speaker wires on some brands does not liked to be moved and will want to settle in

That's also correct.

But what are the Premier 140 capacitors that are replaced with Teflon?

Quite honestly I don't know. I was never one for taking something apart and then being able to put it back together correctly. So, I never popped the hood to look either before or after the C1 modification. I do know that the Premier 140 sounded immediately better after the modification and it did indeed improve further as the caps formed/burned-in.

Sorry to not be any help as to exactly which caps were replaced.

Hi,

The Teflon upgrade will mostly consist of exchanging all the following :

coupling caps 8 x 0.15 uf x 600v
the 2 number 0.15 bypass capacitor in the input ---these do not nec need to be there if you replace the 1uf poly with teflon

the 0.15 bypass caps in the power supply.
For the most part all 0.15 600v polystyrene will be replaced with Teflon.

If you are struggling to read the schematic best to stay away from the board.

Almost all the c1 upgrades follow this basic pattern ----there can be transistor changes to the power supply as well . On the premier 140 I count min 14 caps for changing --do the maths using v cap cutf 0.15 600v as a guide.

Hope the above helps --its just a guide so don't shoot me down if I missed a couple !
