Little Dot Tube Amps: Vacuum Tube Rolling Guide - Page 529

"Matched" is a red flag word to look out for as the LD I+/II/III/IV DO NOT require matched tubes and will not benefit from them. It is a way the seller can get more money for the tubes.

 

The stock LD MK III & IV tubes (GE 5654W) can be had for 55 cents a piece if you win this auction...

http://www.ebay.com/itm/100-PIECES-NOS-NIB-GENERAL-ELECTRIC-6AK5W-5654-6AK5-403-A-6J1-AMP-VINTAGE-TUBES-/271638933330

 

That is a small private auction, I do believe there are other suppliers who sell tubes in bulk/wholesale only and don't list on eBay. With those suppliers you could probably pick up a thousand lot for 25 cents a piece...

 

This thread can be overwhelming with all the info, there is a table on page 77 that shows all the stock replacement tubes that have been tried. One of the best tubes for an unmodified LD is the 6HM5`s I linked, other than that you will need to get into double triodes and octal tubes with adapters and possibly external power supplies...


Thanks, I'll have a look at that page. Was interested in the Mullards but in the Little Dot manual it said some people had experienced distortion with them, so gave them a miss.

"HappyDIY998" engages in "Feedback Extortion"!!

 

The last message to me, from them:

 

====

Hello,

Dear sir, if you say like this, we are willing to refund you the payment fully and not sell this adapter anymore, I do not know what that buyer told you, you can find that we want to solve the problem, if you leave us positive feedback, you will get the same, if you leave negative, we can not control you, please keep in mind, we are the honest seller who want to solve the problem,

now we can tell you one way, we will refund you payment fully if you leave positive feedback, or if you have any suggestions, please tell us, we are waiting for your reply,

Thanks&Best Regards,
Vanessa

Sorry about your continued problems, "JazzVinyl". If through eBay there is recourse (eBay / PayPal), but may not result in positive feedback. Amazon has more influence to obtain restitution for problems. Other transactions where a credit card was used, permit you to file dispute with your bank for goods not received (or non-functional). Problems with adapters may have prompted headf-fiers to go the DIY route.

If any fellow head-fiers have had good experience with a supplier of vacuum tube/valve adapters can you please let us know?

Really too bad they are the only builder of the C3G to 6AK5 adapter.

I didn't like it the moment I saw the chopped off B7G tube as part of the build,  that is something I would do and not expect it from a commercial seller.

 

Report them to eBay about the full Refund "IF" Positive feedback. Leave them Negative Feedback and file a PayPal claim against them.

 

Then tear the bad adapter apart and fix it yourself.

I don't believe eBay will tolerate Seller extortion. If it was me, I would file with eBay to assure the Seller follows thru with their promise to refund your amount, and suggest in your dispute filing, that you be reimbursed for shipping. Once resolved, you can leave feedback, noting that you received a non-functional adapter from the Seller. Either way, I would doubt Seller intent to leave positive feedback...

Yes, I don't think there is any hope for getting this seller "happydiy998" to understand he owes me a working C3g to 6AK5 adapter.

 

I will report them for Feedback Extortion, as they are clearly guilty.

 

And I _do_ want to tear apart and fix it...the question is:  How the heck does it come apart?  I have been inspecting it with a Lupe, but I don't see a way in.  And it does appear that it would be pretty easy to break the glass "chopped off B7G" portion of the adapter...

 

Any ideas on how to get it apart, guys???

I seem to recall that one of our posters contacted happydiy998 and asked them to make this adapter, which they did. So it is certainly possible that if asked, another manufacturer might be willing to make them, as well.

Finally managed to snag an early Tung-Sol 5687.

 

In both pictures, 1956 on the left and 1952 on the right. Notice the flat black ladder plates on the earlier tube.

 

 

Haven't had time to do any comparisons, but after a couple hours, it certainly seems to be a terrific tube. :)

How much are the stock tubes worth then, pennies?

I'm I right in thinking that  page 77 table is only for driving tubes? Has anybody assembled such a table the power tubes?


What is the process for Figuring out what power tubes are compatible for yourself?

Check the manual for your amp. From what I gathered browsing this thread the power tubes have a lesser effect on the sound of the amp.

Looks like the C3g to 6AK5 adapters have been pulled from eBay as there are none to be found...

Aliexpress has them but they look like the same poorly made product from happydiy998 and most likely are.

 

They definitely look to be epoxied, if you could pop out that greenish piece of circuit board, you might be able to push the innards out and examine them.

Might get lucky and find out it's only hot glue encasing the insides...
