Question Whats a good 6L6GC Stereo Amp Project

Hello

I am a new member. I have just recently become interested in Tube Hi-Fi . I have built several tube guitar amps, so I know the basics but still consider myself a novice.

I would like to build a good sounding stereo amplifier. I would like to use 6l6gc`s and 12ax7`s or 12au7`s because of the availibility of these tubes. I have a working Heathkit aa-50 integrated amp for a parts donor.

What I am looking for is advice. What is a good design for me to build. Are there any amplifiers that use 6l6`s that are real "shinning stars"? Somthing that delivers good performance and will give years of listening enjoyment.

Thanks
Glenn

Try http://gabevee.tripod.com . Gabe has a 6L6GC SE kit that he sells, but go to the index at the bottom of the page and a bunch of stuff will pop up. There is an article on a SE amp using the 6L6GC as well as others. Good luck.

That is a prety fine loooking amp but I am looking more for a design/schematic recommendation since I already have a working Heathkit AA-50 parts donor, I am looking for a push pull 6L6 type amp to be recommended for my first build.

Thanks Glenn

Default 6L6

you can find a schematics for the 6L6 on my site, last week i put on a curious "Parallel output push pull" using these tubes, but unfortunately needs a special OT

Uncle Ned has a whole bunch of great schematics on his site at:

http://www.triodeelectronics.com

I am sure you will find some good ones using 6L6's. You can also take just about any p-p amp and substitute the output tubes with the 6L6, just considering the primary impedance of the output transformer. You can use upwards of 400 volts on these tubes.


Hope this helps.

Thanks everyone ,right now the Pilot aa-410 is on my short list. Easy build and good sound from what I gather.

6L6, yes of course, Glenn

i have ever build a 6L6 rusian(triode connected) class A pushpull, drive by triode 6sN7 rusian as a split phase shif, and the gain stage using triode 6sL7 with a tubes rectifier 5U4 with a home build power transformer and output transformer, and this amplifier tone bright, its suitable to reproduce a guitar sound like ibanez, not a fat sound it not so suitable for bluesy sound gibson, try for a pentode or tetrode connected for a bluesy sound, it needs more power

just want to remind you
build an amp for guitar different way compare to build an amp for high end sound system

triode (300b,vt52,211..), pure class a, direct heat tubes, low harmonic distortion, low impedance, ussually suitable for high end

pentode (ef86,el34,6l6,6550..), high 2nd harmonic distortion, overloaded(un matched load, or speaker impedance), ussually suitable for a guitar amplifier

best amp in best purpose
regard

Sorry, got to question the above post.

By that definition the Quad II is a great guitar amp because it uses 2 x EF86 + 2 x KT66 (variation on 6L6). I some how think that many people who use this amp would argue with you, as would any ST70 & Citation users.

Mind you I'm not anti DHT, as I'm in the process of getting the bits together for a 300b amp.

Default kt66

>lilolee

it's a nice having your correction on my statement, yes of course pentode is just the global statement for a great result in guitar amps.

kt66 is the variation in 6l6 but it is known better in a high end amplifier, and also kt88

we have a global line and also we have a special line for exception : and for example is kt66,kt88 etc tell me if you know the others ?
