Millett "Starving Student" hybrid amp - Page 102

Yeah.

...man with those 19j6s going into obscurity the "starving student" is really earning its quotations.
It's great that Nate's gone to the trouble of making some (of the last few?) available.

How sad the 19J6s are disappearing, the SS is a great first build and I use mine all day every day at work.

I have two spare 19J6 which I'll gladly pass on for the cost of postage, but I'm pretty sure than one of them is on the fritz. Is there anything you can do about a tube that adds a humming noise into the channel?

What are the possibilities for this design being updated for some other more easily findable tubes?

A few weeks ago I picked up a pair of NOS Sylvania 19J6s for $12 each at Fistell's here in Denver. At the time I thought it was bit of a rip-off, but grudgingly bought them anyway. Now, I'm glad I did. At the time, I think they had one or two left.

The guy at Fistell's thought it was pretty strange that I was interested in this tube.

Well, it remains to be seen if I just tossed a ton of money down the toilet considering the feedback I've gotten so far on the pricing. I can't believe the backlash over what is essentially $8.

Personally I use the 1/3 rule when I do someone a favor, in that 1 out of 3 times I won't regret it.
However, the people in that 1/3 category are generally great and make it worthwhile.
Also, I take names

I appreciate it

Unfortunately I ordered my tubes this weekend

I'm hoping to get all my parts in this week and build it this weekend. I know once my buddy hears it, he will want one. If you still have some, I'll probably order from you to make his.

I just had a thought, if you have trouble selling the tubes, spend (invest?) a little more $$ and build a bunch of amps. I bet there are lots of folks that would want one, but lack the skills or tools to make their own.

I just wrote in to Jim, and sadly they're now out of the 19J6s.. Still hoping to find a pair to build an SS after term.

Are vacuumtubes.net and vacuumtubes.com both out of em too?

Chances are, so long as the dealers know people are after them, a pile of these will turn up from out of a warehouse where they had been forgotten. Or, what would have constituted that pile were all trashed as useless. You would be amazed just how many random warehouses with thousands of random tubes there are. In some cases, the cost of sorting and storing is more than the perceived value of the tubes, so they end up getting trashed.

Here was an old thread about someone selling 1.5 to 2 million tubes on ebay for a quarter million dollars. This wasn't even their large warehouse, which still exists. Nobody is going to sort through all that garbage to find a couple hundred 19J6's.

They pop up on eBay quite often; 3 pairs available now.

I did enquire with them about overseas shipping, but didn't get any reply.

Any pics or more specs on your build, seems similar to what I want?



Also why are people choosing different values for C1 & C6 (like 680uF and 470uF), why not same? Am I missing something about the circuit.

Also does putting a cap parallel across the DC input "quiet" down the noisy walwart and provide some "sink", any size recommendations? I'm seeing ~470-680uF

Also what the general consensus on output caps (C3,C5) 330-470uF? Bypass w/ a film or just leave the films for the Cathode's (C2,C4)?

I was thinking my setup (maybe):

C3/C5: 470uF BG's/Muse ES/--- ... possibly bypassed .22 or .47uF VitQ's or K40Y's
C2/C5: .22uF VitQ's
C1/C6: 470uF Muse KZ
C"0"(DC In Cap): 680uF Muse KZ

Yeah that's fine, it's the one I have.

Thanks.

me != MOT, and I don't lack for projects to occupy my time.

And I'm sure that more will become available from time to time as dealers acquire more stock. There just seemed to be a glut of folks that were having trouble finding them recently.

Wow, I guess I got lucky then. One place I called said he used to throw them away because there was no demand for them! Now he has none in stock. Make you wonder, are there any other good tubes out there that are sleepers waiting for the right person to come along and build an equally good amp with? I wish I had the skill to do so...
