Tube Experiences with specifically ET7 and possibly ET5 pre's

This is not about issues with but about listening experiences with Tube swaps with ET7 or ET5? If you have swapped stock and had an experience worth discussing please post.

Re: MF2500 throwing 68 DCvolt out on right channel

It plays extremely well. Had a ground loop problem with one of my preamps. That was fixed and now it is dead silent and absolutely no transformer humming also. According to my knowledge the only "soundwise" difference between a 2500 and a 2500A is the new discrete rectifier diodes. jahatl513 - is i...

Re: New ET-7, and my name is not Roberto

I have a calendar and each day I have listed the Classic 120SE's hours and the ET-7's as well. You'd think it would be the same but I have had a really great time with the MF2500A I had rebuilt by CJ in February of this year, so the Classic 120 is going to fall behind. More Later.

Re: MF2500 throwing 68 DCvolt out on right channel

bambadoo - If I get the occasion I will open it up and take a pic. I imagine you are scratching your head on this and want to know more. If you are interested I would call and ask for Keith at CJ. Since the work is somewhat fresh, you can use me as a reference to your question. There's more to it th...

Re: New ET-7, and my name is not Roberto

Thanks Roberto, you see I was joking in my Subject matter, since you have had such a roll with the ET-7 I thought it appropriate to start a new thread. Yes, I am familiar with the drill and thank you. What I've found interesting is that you can actually, or I can actually tell that something great i...

New ET-7, and my name is not Roberto

I just received my new ET-7 yesterday. In addition, the shipment included a new Classic 120SE. It is Saturday night, and on Friday I unboxed the ET-7 and hooked it up to my MF2500A while I was busy cleaning records sonically. I'm coming from a Premier 16LS2 and Premier 17LS. It's too early to tell a...

My New Classic 120SE

Hi All, I just wanted to go to the rooftop and shout out that I have this night fired up a new Classic 120SE and it is paired with a new ET-7. I'm about 2 hours into it and I should still be holding my breath. First impressions have nothing to do with the fact it is as quiet as a church mouse, no hu...

Re: MF2500 throwing 68 DCvolt out on right channel

Bambadoo- No, but its hidden cryptically in the replacement parts I suppose. I did not have it when it had blown so I could'nt tell you more. Update- I put it on my ET-7 yesterday (just got a new ET-7 and a new Classic 120SE) and it sounded outstanding. Keeping everything at fairly low volume as the...

Re: CJ PV-12 advice needed

I have had a PV12, but never this issue. I would get back with jeff F and relay to him what you have done as a troubleshooting method. I'd refer to send it back to them to have them replace the tubes and to test it. Question; were they ever able to recreate it in their labs when they had it? You did...

Re: MF2500 throwing 68 DCvolt out on right channel

Yes, Keith and I worked out a plan to restore it to a glory that its former could not obtain. You see I bought this at estate the same day I purchased my Premier 350. Here is what was done to it. No expense was spared (absurd or not) New: Main Caps, Bridge Rectifier w/ discrete slow diodes, differen...

Premier 17LS2 vs ET5

Does the 17LS2 inherently have Teflon caps as part of the factory built?
Would anyone with 17LS2 experience give their impression of it. My baseline is 17LS and 16LS2 and not ET5.

Re: PV 12 Phase Inverting?

It sounds like you have the right answers and the seller was not BS'ing you. With the actual literature link to PV12 you do see it on page 6 that it says phase inverting and then how to handle it. Good Luck!
