.......... also the Raytheon 7F7's are incredible value tubes. They are very clear and give a live concert type sound in contrast to something smoother like Tungsols.

Good to know, I want a very Solid State Tube sound for my Audio TEchnica Headphone lol

 For SS sound another one to consider would be any Sylvania 6SN7 eg GTA, GTB, VT231, although I've heard some described as lush, that is the last thing I would describe the ones I've heard which I would say are dryer and sparklier than most other tubes.

Thanks for your reply Baronbeehive. Do you think the 6su7 would fit in the littledot 6? I have been reading good reviews of TS6su7gt.

Yes they are simply military versions of the 6SL7 with factory matched triodes. I had these at one time but could not detect any sonic differences between them and the 6SL7's so that's what I use now because I couldn't justify the high price of the 6SU7's.

Thanks again, also on the power tubes, I have a quad set matched of 7236s but if I were to lose a tube, can I put another tube in that is closely matched or do they all have to matched exactly?  

post #1012 of 1303

Closely matched is okay as long the meter shows the same. Exact match is not possible since the tester does not know the exact operating points of the amp. I had power tubes that tested okay but did not work in the amp.

post #1013 of 1303

Hum, I was thinking about graphite, is there any 6336A owner here ?

I don't think it's safe to plug a quad of those, but anyway...

My Little dot MK VI+ with Svetlana 6N5S power tubes (1967) and Shuguang 50 years Treasures CV181-Z driver tubes (needed socket savers to enable tubes to fit as the aluminium rings have a smaller inner diameter than the tube base outer diameter)

Me thinks the SE buzz/hum is to do with a grounding issue on the circuit of the way it's designed (circuit/pcb ground is different to chassis/rca ground). I had some humming issues on SE before my unit was modded and inspected by a local tube amp builder, amp came back and the noise was gone. It's been over a year and I haven't used the amp but it's in pieces so I dunno. Anybody want VI+ scraps for $200? lol

I'm stil searching coupling caps for my VI+, and don't know what to choose...

How did you make your choice people ?

 

I'm skeptical about russian PIO, because I don't know what I'm buying... they can be good or bad, or very different from one to another.

Mundorfs must be a good choice, the Supreme Silver in oil seems to be neutral and dynamic, but they are costly...

I'm thinking about the high rated Audyn True Copper, they are affordable, and despite a thin bass highlight they may be a good choice for such an amp...?

 

All advices and thoughts are welcomed. Maye I'l post in the capacitor orgy thread.

One can never go wrong with Russian pio's, they sound good and are cheap. Do forget some esoteric coupling caps have a bigger affect in crossover applications rather than in the coupling position in the amp.

If you don't want to spend hundreds on upper end V-Cap, Duelands and Mundorfs, look at the Obigilito Gold series, Jensens, Jantzen and the cheap but good Auricaps.

I bought 4 of the Mundorf Supreme Silver Gold Oil capacitors and sent them to Littledot, had them installed in my amplifier when it was built. I am VERY happy with the result. But I can't make a comparison with the standard capacitors because I have never heard what they sound like.

There not bad. 1uf will give more bass.

How did they managed to fit those inside? did they remove the fans? 

I would love to see a picture of the inside.
