Little Dot MKIII Tube Rolling - Page 7

post #91 of 2868
I've been looking for some additional power tubes, and cannot seem to find any 6H6P-I tubes. I was at work when the last batch sold on ebay.

A search on Google doesn't turn up much. In fact, I emailed a Russian seller who had some and he quoted me a price of $200 for 6 tubes. He went on to say that they have a $200 minimum.

Right.

Anyway, can somebody please list all of the known tubes that are a direct replacement for the 6N6P-I? I've seen the 6H6P discussed here, but I noticed that that specs were a bit different. Are these OK, and are there any others that anyone has confirmed work in the MKIII?

Also, if anybody has a spare pair or two (6N6P-I) I would be more than happy to buy them.

I bought these in December:

RUSS TUBES 6N6P-I = ECC89 = E182CC Lot of 10. NEW! RARE - eBay (item 260193828112 end time Dec-20-07 14:40:59 PST)

They are correct. The eBay seller illustrates the pin outs. He has had several sets of 10 for sale and likely will again. Try emailing him.

The Russian tubes are marked 6H6n or 6H6n-N with the capital N reversed.

I know, that's the auction you linked me to earlier, thank you. Unfortunately, I was at wok when it ended. I did email him to see if he has any more, but I am still curious there are any other tubes that folks have verified to work in the amp.

In the meantime, I'll continue watching ebay to see if he lists any more. I certainly don't want to pay Little Dot $20 per pair + shipping for the same tubes.

I'm getting to the point where reading threads like this has gotten me really curious and I'm ready to order a set of tubes to roll in. I've read several posts from people who have gotten many different tubes to try out and I'm wondering which you preferred out of all of them. I'm looking to buy a set of tubes off ebay to try out but I really don't want to buy 3 or 4 different pairs to find the best out of them. I'd rather just hear about one type and brand of tube that most of you have preferred over others. For instance, right now I'm leaning more towards the Amperex 5654 tubes since ethebull compared them to some others and preferred these."

So, to sum up, what is the best set of tubes you've tried out so this lazy tube roller can have an easy upgrade ;-)

As the Mullard M8100 are burning in, it is definately smoother then stock&RCA. Left them for dead straight up. The mids a so full and warm, and can get to the upper reach with ease-every style of music I throw at it and its just well controlled even at ear bleeding vol. The RCA 6AK5 are very efficient on power (had to back off) and has a more airy sound along with a big headroom: great for live recordings. The "genuine" NOS Tung-sol 5654 Black Plate are on their way (hint:there's still another pair left at vacuumtube.net)(thanks to Negatron for the praise of these tubes) along with a pair of WE403B too. So happy days!!! think that should be right for the EF95 family. Start on the EF92 next.

As the RCA are the only pair fully broken in. I go with that for now.

I checked and didn't see the Tung-sol 5654 Black Plate tubes. Must have sold already

Call them.

They can tell you what they have in stock. I think their price lists at the web site only show the tube number and price, not the brands or quantity in stock.

Ended up finding some Amperex EF92's for a reasonable price. I'll post my comparison to the stock tubes here after I receive them and they've had some time to burn in.

Or one old box that says 'Mullard' but contains something else.

If packaging and mailing aren't a problem for you (they are for me), you should buy the lot and sell to HeadFi'ers for a buck per tube plus shipping. Everybody wins!

Too late, they're gone.

I didn't figure they would last long at that price. It's almost robbery.
