I am going to be selling off most of my rare 6SN7's including TSRP's,11 matched pairs 1942 production. Sylvannia Chrome Domes and Metal bases, Bad Boys, RCA Black Glass and Red Bases. PM if anyone is interested please. No longer using 6SN7's.

Ah thanks, if anyone wants to sell me their Takatsuki rectifier or something similar, I’d be interested.

I have a pair of Tan 274B's. PM me if interested.

Has anyone had any experience with the Full Music 274b? Those aesthetically look amazing.

Ok guys, I’m planning to get the Wa6 amp and upgrade the tube to Takatsuki 274. I plan on getting the tube by itself off the Woo site. Wonder how it’ll sound.

I suggest you get the WA6 or WA22 or WA5, WA33 first, then try to tube rolling.

 

[Jacobal]

I’m changing my mind on the Wa6. I’m actually getting the IHA-1 amp. A single 274b upgrade like Taks or Full Sound should be good enough. No idea if the optional transformer upgrade makes a difference.

Cute amp. Lundahl transformers are the best and will make a difference.

I've heard a custom amp with three Lundahl transformers

Have you compared the amp side by side with the upgrade and non-upgrade?

The upgrade for IHA-1 only includes one transformer replacement from Moonaudio for 250.

Nope. Not really easy to do.
The Transformer has been noted to have a extremely low noise level.
The amp with Lundahl transformers I heard sounded smoother, warmer and more detailed than a WA5 that was beside it.
It is the best sounding tube amp I have heard. However it should be tho. The guy sunk $9K on it.

So true. Never compare orange to apple.

That's 300b amp made by Glenn R, the specialist tube amp designer / builder. He is currently making me an OTL amp that runs 6 x 6BL7 or 2/4 6AS7 or 2 x 6336 and is switchable for 6 / 12 or 25 volts. There's a boost switch for 5998 tubes. Driver tubes are a single *SN7 or a pair of Siemens C3G. It will have one Lundahl transformer.

If the Glenn 300b amp sounds more detail than the WA5, then it must be something because I heard a WA5 source from Yggdrasil at a recent meet and I reckon it's right up there for end game status. I also heard the Susvara driven by the WA33 at the Sydney HiFi show. That's an out of this world sound.

We had the Glenn 300B next to the WA5. It was no contest. Not even close.
He has sunk a lot more $$'s into that amp since then and it is sounding even better.
He had the transformers dipped and changed rectification to SS with soft start option (that was a great move).

So I purchased a new 2nd Gen WA6-SE. The stock power tubes are the 13DE7. I was planning to get some 6DE7s when one of the tube sellers told me that might be a problem. If there's no voltage switch, then any six volt Power Tube will burn out quickly. Is this the case? I saw the 6DE7 as being good to go with the new 2nd Gen.

Wish I was able to hear those 2 amps side by side. The 300b must be one great sounding amp.

I also went with SS rectification for my OTL amp, based on feedback by Glenn and a few others.

Ok I seem to have a problem and Im not sure if its the tubes or the adapters - Im using the Tung Sol 6C8G tubes with adapters made by @2359glenn . The tubes are perfectly matched. This is on the WA5.

When I first plugged in the tubes, the left side in the headphones was much louder than the right - I thought the tubes are defective/mismatched, however when I swap the tubes (keeping the adapters still in the same place), the sound gets much more balanced, but very slightly tilted to the right (as opposed to a much bigger difference). It's extremely strange. Swapping the adapters has yielded no results. Anyone has any ideas?
