can really be confusing LOL!! But seriously the above posts have your impedance questions covered.

I have no patience for any of this!

This Triode/Pentode crap with Bob Latino and others just drives me crazy.... the amp does not operate in Pentode mode. It operates Ultra Linear which is more similar to Triode than Pentode. I have no clue why Bob calls it Triode/Pentode switch.

Kevin deal is right just about everything in the Jolida is entry level quality.... so is the price.... thing is Primaluna is only marginal step up. What I love is he basically calls the Jolida a POS and but he'll sell you it LOL!

Stop messing around and get something that will really sound good!

Here did a print screen of this from the manual

Email me and I'll send you the manual I have its named TercelmanualREv3 its too large to upload here. craig@nosvalves.com

who me and this forum software is flaky as all get out.......

There is just too much hate in the world....

Aahhh BS your just wishy washy... hell I'm convinvced your about 3/4 deaf

What about the attenuators you want to talk about? You ask the strangest questions sometimes LOL!!

I hope you mean 7308. A Primo 6DJ8 will sound a little better than a 6H30 I don't believe Mark (juicy Music) or I ever said it wouldn't. The thing is the headache and expense in finding a quiet primo choice 6DJ8 is not a pleasant undertaking for everyone. I have about 16 nice choice vintage 6DJ8 that I used to use in my BBX's and they are all noisy a pair really nice PQ Phillips 7308 gold pins that became noisy on me after multiple years of heavy use... its a damn shame. I'm a cheap bastard at heart and often run my gear 16 hours a day I refuse to plop down hundreds of dollars on a tube I'm going to use like that. So I use the 6H30..sound almost as good and is always quiet for $30. Nope don''t believe in those 70's and 80's super tubes either... I own 2 of them and they don't sound any different then the modern $30 sovtek or $32 EH gold pin.

Yup that gets me to post ....it's pretty hard not to point out you did a complete 180 in this thread... Before you said.. "Since I got my NBS I have not used my Peach. The NBS is quieter for sure, but sounds better to me as well. The Peach might have a little more 3D effect. The NBS allows use of the lo and hi Z outputs simultaneously which is a nice feature to drive a sub." So which is it LOL

you buy them and I'm closing up shop.......... LMAO

I'd hope so I bet they both sound great in their own way.

Yup 5 miles inland. Shop has barely Klipsch Frankenscalas, my living room has stock Bells except new Type A crossover with Vcaps from Dean. I also have a garage/shop that will have Tannoy Studio Monitor in it when it's done. My upstairs office will have some small single driver bass horn cabinet speakers I don't recall what they are called bought in the garage sale section a few years ago and still haven't heard them LOL!!. The garage and the upstairs office are a work in progress. So much to do and so little time/energy! Getting old really sucks!

First things that come to mind..............Butt ugly and way beyond diminishing return...

cardomatic tube tester at the opening.

2 set active outputs are used for power subwoofers or when bi-amping. Not all that unusual at all. I think you will be able to use both set of amps as long as you're careful. I would confirm that having both sets of amps attached is not causing a load down/impedance problem with the preamplifier by pulling the RCA cables from the preamp for the UNUSED set of amps while you are listening to music to see if you can hear any audible difference or sound level when you lift the inactive set of amps from the preamplifier. If pulling the RCA cables while listening gives you pause then your going to have to use your ears and AB the setup. Craig

I was moved to a larger home in the exact area I grew up in. My house is about 7 miles north of the town of Oscoda. I'm now just a few miles off Lake Huron.

Rich, Should be pretty easy to figure out what the switch does get me a close up shot of the switch area inside. Also if your using the preamp right now and only have one set of amps attached flick the switch and see if the sound goes out to the attached amps.

You don't need to do all that math.... I'm sure the amp is designed to be bias between .40 to .60 at the 10 ohm resistor on pin 8. THAT PIN 8 VOLTAGE IS THE BIAS CURRENT MEASUREMENT. When you adjust the bias control you are actually adjusting the negative voltage on pin 5 which causes the current to change as you measure it at the pin 8 10 ohm resistor. If you are truly getting a measurement of 15 volts on pin 8 you mostly destroying your output tube/tubes you should not be recklessly adjusting those controls up and down. Adjust them to keep the measurement on PIN 8 in a safe range (between .40 and .60) The only other thing you should watch for is red plating on the main inner structure of the output tubes. If you see any lower the bias measurement at PIN 8.

I know all too well what it's like to be busy.. but if your making trips to Omer you're well over half way to my place. I'm located about 7 miles north of Oscoda.

Dave, I used one of those mapletree preamp for few years way back when maybe that is how you ended up getting one? I think if you ask loyd the owner he would tell you get a pair of 12SX7's if you can find them. I know someone that has a pair...maybe you need to take a trip north sometime.
