If you're handy with a soldering iron you can make your own 6BG6 adapters using this kit (http://www.vacuumtubes.com/6BG6.html). The seller will sell the adapters separately of the 6BG6GA tubes he's selling, and may be able to assemble them for you for a fee if you ask. The SND Tube Sales...

6N8P = 6SN7

My stuff. I'm a rank beginner, so right now I can only play some basic chords and vague-ishly musical sounding squanks! Ibanez RGAR42MFMT Sano 16WR Fender Vibro Champ XD

I added a set of Dekoni sheepskin earpads to my T-X0 cans that I currently listen to through a Project Sunrise III hybrid amp. I think the pads help out a lot with making the bass less muddy and more accurate.

I have some that will sell for decent money on the auction site and am posting time when I have time. However, I've many more, mostly TV, tubes that are nearly worthless nowadays. I have an e-mail out to a local electronics recycler to see if they will take them for disposal if I decide to go...

Byzantine - The Cicada Tree

I've hopped onto the 6BG6 bandwagon. I bought and finished building a pair of 6BG6 to 6L6 adapter kits from SND Tube Sales, then scrounged up a pair of strong-testing Tung-Sol 6BG6Gs from my stash. One is relabeled for Emerson and the numbers don't match, but after a couple of listening sessions...

I don't think true ECC31s (also known by the British military designations NR73 and CV1285) were ever made by anyone but Mullard. Someone in the Feliks Elise posted a photo of a QTL-rebranded Mullard ECC31 here...

I've discovered another reason I like this amp - it can bias and operate with some very weak preamp tubes. I have an authentic Telefunken ECC803S in my tube stash that tests extremely weak for emissions on my tube tester. Like, almost dead. It works great in the APPJ and sounds just as sweet as...

Sipping a little Green Spot Chateau Montelena at the moment. Lovely stuff and a great addition to the Green/Yellow Spot family.

I don't believe such a beast exists, though undistorted metal sounds a lot like surf rock. Especially black metal. There's a few of these undistorted metal songs floating around YouTube. Played straight Sacred Reich's Surf Nicaragua and M.O.D's Surfin' M.O.D. are the closest things I can...

Any ECC88/6DJ8/6922/7308 will work in the Ember. 7DJ8/PCC88 too. 12DJ8/8416 will not work since those are 12V tubes. I haven't had any channel imbalance issues when using 6DJ8s in my Sunrise except when there's a major imbalance in emissions or transconductance between the two triodes, but...

I have a Mullard CV1285 (military ECC31) that I sometimes use in my Project Sunrise III amp. At 950mA the heater draw is a little over the 900mA rated supply current of the Sunrise, but so far the laptop-style power supply is holding up. I use a ECC31 to ECC88 (6DJ8) adapter to make it work in...

I've not had a good, long listening session to my T-X0s yet. I do agree with first impressions that they are on the warm side and have great build quality and comfort. I'm not expecting them to outdo my HE-500s. We're talking about entry-level vs. former penultimate. I bought the T-X0s on a...

Not sure if it's been discussed here already, but the octal base equivalent of the 14AF7 is the 12AH7GT. It will need its own adapter because the plate and cathode pins are flipped compared to a 12SN7. Probably better going with a 14AF7 and loctal-to-octal adapter, since you can also try 14F7...

Mine too! :ksc75smile: I'm at work though, so I'll have to wait till tonight to listen to them.

w00t! Expected delivery date: Wednesday 10/4!

6Q5 is listed as a Thyratron tube, not a pentode or kinkless tetrode. I don't think they would have worked anyways- a quick Googling shows thyratrons aren't suitable for amplification, being more of a switch. Unfortunately, they appear to have little use in modern tube circuits. To throw in my...

I noticed an issue with my amp, that sometimes the left channel would not work or play loud static unless the preamp tube was cocked a little bit to the right. It was also more microphonic than I remembered, no matter what tubes I used. I discovered the #8 pin socket needed retensioning, and now...

The APPJ's preamp socket supplies 12.6V, which will severely reduce the lifespan of a 6.3V tube like the 6DJ8 because its heaters will run way past spec. In the APPJ you have to use either a dual voltage tube like the 12AT7/12AU7/12AX7 or a 12V version of a 6V tube in the preamp socket. If you...

6W6GT has the same pin-out as the 6V6GT. There's actually only 6 active pins on a 6V6GT/6W6GT (7 on a metal can 6V6, the #1 pin attaches to the shell for grounding). The extra pin on the right tube is not connected to anything. You should be good to go.

All the modding I've seen of this amp have been to improve the sound signature, not for repair or reliability reasons. For PA1502A users who've experienced failures, do you happen to know what failed and/or have any pictures of obviously failed components, like bad caps?

I have one of these 3.5mm to RCA cables. https://www.newegg.com/Product/Product.aspx?Item=N82E16812123070 I think the issue with noise is not from external interference but from poor grounding and/or internal interference from the source device (my PC's onboard audio picking up interference...
