It seems that some tube dealers are running low on 19J6 tubes.

I just talked with Radio Electric Supply (Vacuum Tubes Radio Tubes - 5,000 different tubes in stock - Over 10 million tubes!), one of my favorite tube dealers. They have a few hundred 19J6's in stock, and are getting more.

There appear to be plenty of them at wholesale suppliers, so even though the "usual sources" may run out, I think they will get more into stock. It historically is a very low demand tube.

I just finished building one of these. It sounds just delightful. I'm looking forward to spending more time with it.

I used a wooden 6"x6" "frame" box from an art store and a copper clad board for the top. I followed the photos of Pete's wallet box layout with little shame.

I would welcome advice on capacitors. Due to outages at Mouser last month when I ordered the parts I have 470uF 63V capacitors everywhere except C2 and C4, where I have 220uF caps. All Nichicon aluminum electrolytics.

Sorry for the poor photo -- I'm a poor photographer. When I dig out the cable for the camera I'll use that - in the mean time a cell phone camera shot.

Thanks sincerely to Pete and Nate for offering up this design and all the details around building it and for the kind advice and encouragement on this forum -- I have derived the greatest pleasure building this amp.

Not sure if this link will work, but it's the 6x6 wood finish version of this item from Blick art supplies: Ampersand Gessobord Shadow Boxes - BLICK art materials

Looks like I paid about $8 (I've had the box for a while -- it had something else in it for a while).

They recommend placing candles inside it... Do they sell home insurance as well?

If anyone else has assembled the BOM on this project and is looking to bail out, please let me know. I wouldn't mind building one of these for fun... its been about 15 years since I built my last amp!

Not to beat a dead horse but no one intends to make a PCB for this project right? Thanks...

I believe the focus is on encouraging the P2P version for the time being, but who knows what the future may hold?

I second Pete's recommendation on using vacuumtubes.net (Radio Electric Supply). Roy and Dale are great guys to work with - very knowledgeable, too.

I'd really appreciate any advice folks can offer on capacitors - I think this question got buried in my last post:

Nice build, royewest. I spy some Bottlehead gear just behind it. THAT is the place that got me into this DIY mess!
Building is such a great adventure.

They're not axial, which would make them easier to use in P2P, but some 0.1uf - 0.22uf Wima MKP10's would be ideal, I think. Mouser should have plenty and they don't cost too much.

I had very good results with .22 uF MKP10s both for coupling and for bypassing the output electrolytics.
I also had very good results using .12 uF BC Components 416s (Digikey) in the same way.
I actually prefer the BC Components.
