Anyone have a bright sounding tube with lean bass recommendation for me? I could go for that right now. Thanks no bass monster tubes please

Take a look at the Westinghouse 6SN7GTB Black Plate D Getter. These tubes have an airy neutral sound with a great soundstage, and were quite popular with the Lyr 3 crowd (me included). They can be found quite often for decent prices, and if I was looking for some, I would seriously consider this pair, from my favorite eBay seller.

A new production tung sol (it has redish base if memory serves correct) is bright and lean on base. Tube depot sells them for cheap.

That one and the Electro-Harmonix. Both carbon copy builds (minus the base color) and made by the same company.

Philco didn't make their own tubes. Most were made by Sylvania. If I am reading the date code correctly, "2 U", that tube was manufactured in the third quarter of 1942.

It's a Sylvania. Great tube!

Here are a couple of notes from my tube travels:

Keep in mind that I'm very treble-sensitive. YMMV, as always.

Many of the Melz tubes like this one are not bass heavy by any stretch of the imagination. Superb mids and highs.
If the use is in a headphone amp, think about Beyerdynamics, they are not for everyone and I modded a couple pairs just to up the bass a bit.

Easy. Philips ECG. Bright, aggressive, and no audible bass below 60 hertz.

I can certainly make you an owner’s manual but I would have to charge $10 a word. The amp was free but a manual would require some thought since you wanted the amp built sideways.

You have already messed with the only things you have access to, hard telling what kind of strange tubes you have plugged into the poor amp.

I've only tried tubes that fit in the sockets without use of a hammer. You're being way too hard on me.

I put you on the same level as Finnegan when it comes to messing around with things you should not.

I consider it a compliment that you've elevated me to the level of Finnegan! Somehow I feel better now.

I have several 6c8-G’s but the only one I could find easily is a JAN RCA with round plates.

From memory, I believe the 6C8G have a higher output than the 6F8G, which would be great for mid to low impedance headphones.

Luckily the Incubus does well down to fifty ohms or so so I have been using OPPO PM-1 and Alpha Primes with it. I would have to think about a tubes gain affecting output impedance, OTL's generally run a higher voltage and less current, but if the current were increased I suppose it might help. It's been a long weekend so it is time for music and some single malt.

Enjoy... Well deserved break.

BTW - Incubus drives my 35 ohm Hifiman Arya HPs wonderfully.
