Yes, in the notes section of the checkout process you can specify low, medium, or high settings. Regarding advantages and disadvantages, the higher the number the higher the headroom.

If your amp uses 6L6 tubes for power these should be a great upgrade/replacement.

If your amp calls for 6L6 tubes, these will work in your amp.

These are the tubes I run in everything that runs 6L6 GCs. My '78 135 UL Twin runs over 500v on the plates, and these are the ones that can take it! Very 'musical' and long life. I play pedal steel, and clean is king. I've run a LOT of current production tubes, but these are the ones I always end up with in my Twin, BF Bandmaster, and some old single tube amps.
I mistakenly ordered a set in the wrong heat range once, and AP was good about the replacement.
Nothing but good things to say about these tubes and Amplified Parts!

Just picked up a apex matched quad from amplified parts for my Revv Generator 120. Great tubes, sound great! I have used them in other amps I have owned Randall Diavlo 45h and Randall Satan 50. Never had an issue

Very nice sounding tube in my super reverb. Only reason gave them a 4 is one tube drifted quite a bit after about 3 months. Sent them back and Amplified Parts replace right away, even though it was couple days after 90 day warranty. I was extremely impressed by their customer service and will buy tubes thru them again for sure.

It is a good tube,but it does not have as much power as a regular 6L6GC... Also the amp you use it in makes a huge difference..In my 63 Bandmaster I need to turn it up more to get the same volume as a JJ or any other "new"6L6GC tube..If you use GE 6l6gc then you know what I mean...It is a very good tube,well made...It just doesn't have as much headroom..Just to let you know....

Replaced some mid 80's Jan-Philips 6L6WGB's with these Tung Sol 6L6str's...very comparable as far as sound. I'm very satisfied. Hopefully they last as long...been running the Jan's for 10 years.

There's a number of things to really like about this tube... I can see it as a Go-To for amps that have their 6L6's hanging down.

The short bottle has the Micas braced in a way that not only prevents side to side movement, but up and down...

There's plenty of power in this tube... the sound is strong and articulate. I think my hopes have come to be.... A tube that has the durability of a Sovtek 5881WXT, with a rich sound.
