Theatre Bypass Mod for CJ Preamp?

I am about to aquire a CJ tubed pre amp for my system. The deal is too good to pass on. My original plans had been for an Adcom GFP-750 based on the feature allowing my theatre controller to bypass the pre amp. Does anyone know of a reliable tech that may be able to provide the same feature on my CJ pre-amp? I am thrilled to be able to make the step to a tubed front end, but at the same time really concerned that it may be a moot point if I cannot integrate it smoothly into my system.

I for one, think the theater bypass is not necessary at all. I have a CAT w/o such feature.What I do is take a set of ics. Plug them from the "fronts-out" on the processor /into an input on the pre. My cdplayer goes into the cd input my HT fronts go into any other input/say aux or whatever.(just not the phono).So when listening to 'ht' I just go to aux input. Do the ss level from the pink noise test / from the processor. I just remember where on the volume pot needs to be. REPEAT;change to the aux input/change the volume acordingly each time you do "HT" Not such a big deal.

I'm glad this question came up! I've been having the same delimma! Would it be possible to use a dvd player for both 2 channel and ht duties? If so how would you hook that up?

Thanks ... depending on my wife's ability to follow the procedure ... that may actually work. My only qualm is the presence of two volume controls in the signal path and the possibility of the mains (now fed through tubes) sounding VERY different than the rest of the system. The CJ is a little older and I think darker than the THX processor. I'll have the system together this weekend and will post my results. Still hoping to find a good tech just in case.

Not sure that I understand your sonic concerns.Any 1/2 decent 2 ch pre amp should KILL the sound from a proscessor's preamp.Do we have a decent 2 ch amp?/or are we using a 5ch affair? The 2 ch pre is only a 'half' of the equation;a good 2 ch amp,being the other half.
Streetman:I have a Pioneer Elete with 2 coax outs. One is for DD,DTS/it goes to the dig.in of the processor.The other is the PCM/48,and that goes to my dac input for 2 ch.
