How is the community here? I think it's been about half a year or so since I was here. Ever since I got my Singlepower Extreme with Monarchy M24, I felt "done." Since then, I have gone through some financial hardships that pushed me to sell much of my pc stations as well as some other things. But I never sold my musical treasure for fear of never able to find it again. Thankfully, things picked up once I found a superb job (best job I've ever had to this day), and slowly started to build myself up again. To b ehonest, and this may sound very silly to many, music pulled me through in some very hard days... the power of music is incredible! But that's another story...

And yes, for the curious, I am still feeling "done"!

My question now comes to tubes for these two devices. I have come across some tubes from a friend as well as some I never used when I originally bought these two beasts.

As for headphones, I use the MS-2 and the Senn HD-580.

I'll be preparing a list of my tubes, but just wondering if you guys are still available for help...

Sorry, no one available any longer.

This is an auto response.

Jam your funny, somebody here should be able to help or point you in the right direction. Get the list ready.

I don't have an SP Extreme, so I can't talk about tubes, but are you sure you're done? Ever think about buying power cables or better ICs?

In addition to the stock driver, you can also use a NOS 6SN7, 6SL7, 6188, 6SU7GTY. With optional ECC type 1 adapters you may implement the 12AT7, 12AU7, 5814, 5965, 6414, 6829, and 7062. Or, our ECC type 2 adapters are also available for the 6ES8, 6DJ8, 6922; 6DJ4, 6DJ8, ECC189, ECC88, E88CC; and Osram PCC88. Our third adapter type will allow for the implementation of the 5687, ECC182, and 7119. Other adapters available include 6CG7/6FQ7, 6GU7, and another for the 6350 and 6463.

Output tubes

The following NOS output tubes are available additionally for purchase: Raytheon 6080; GE 6080; Bendix 6080, 7802; RCA 6AS7; Tung-Sol 6080, 7236, 2399; IBM 5998(straight bottle), and Tung-Sol 5998(shoulder type).

Extreme

Gain: 6SN7GT

Output tube:6AS7G/5998/6080 and some rare types like the 2399. Some Extremes are set up to use higher power tubes like the 6528. The higher power tubes use tubes with much higher heater current draw, example 6AS7G =2.5 amps vs the 6528 = 5.0 amps of heater current draw. Make sure you know what type of Extreme you have. The newer Extreme's have a seperate power supply for the high power tubes.

Gain tube adapters ....

Loctal 7N7 .... replaces 6SN7GT with 7N7 (three construction types) or 7AF7 short bottle round plate.

ECC type#1: replaces 6SN7GT with 12AU7/ 5814A etc...,12AV7/ 5965/6414/6829/7062, 12AT7/6201 and 12AZ7A. There are other tubes that have this pinout but most have to much voltage gain.

ECC type#2: replaces 6SN7GT with 6CG7/6GU7/6DJ8/6922 and several others like the 6BK7/ 6BZ7/6BZ8/6FW8 etc....

2C51 adapter .... replaces 6SN7GT with the 2C51/ 5670/ WE396A/ 6385 and 6854.

The Extreme's 6AS7G type output tubes have a very low mu/ gain of 2. I find the higher voltage tubes seem to bring the amp to life dynamically. But the ECC32 and 6GU7 are lower gain and work very well.

Thanks to Single Power and sacd lover.

ooh, thanks for the link to that spreadsheet! very useful. If I have any questions, I'll ask there instead, so as to keep the whole issue consolidated in one thread.

Thanks, guys!

As far as being "done," yes I am.

I will try IC's later on in the future. I want to settle on a tube combination(s) prior to experimenting with other items that will have a lesser impact on sound.

I am not discarding the value of IC's, just saying that they aren't my priority at the time.
