Pictures of the Philips 807. You can see 'USA' on the tube glass as well as printed on the box but the getter is the typical russian flying saucer. Also the sound is 'thinner', without the lush tone of the Radiotron / Sylvania 807.

The more the merrier. :relaxed:

If you're exploring 807, have a look at this too - 5B-254M CV428 Same rating as the classic 807. And cheap too and lots. Just have to get the adapters. https://www.ebay.com.au/itm/310087990401

Holy smoke. A true tube collector.

We're 4,000 kms apart. :relaxed: He's in the west and I'm in the east.

About the same price. Cossor and GEC 807 are probably the same but I have no way of confirming that.

Australian dollar is dropping. Everyday I look at those tubes, it cost a few dollars more. :relaxed:

Discussing GEC 807 with @OctavianH , his opinion is both GEC 807 ATS25 and GEC VT60 are good and legit but he has ATS25 and that to him sound like the good old GEC tone. :relaxed: So I bought the ATS25. https://www.ebay.com.au/itm/305133735041?

No question is silly. See Eric's explanation below. UltimatE is designed for the low voltage and high current yet an audio power tube - 6Y6G. 6Y6G is special but it is still an audio power tube. Incidentally and fortunately, and luckily, the setting for this 6Y6G is also good or workable for...

A haircut. :ksc75smile:

You say you prefer pentode and then say KT88 is really good. KT88 and 807 are Beam Tetrodes. :relaxed: The way I look at it, there are very good tubes in both pentodes and beam tetrodes. I'm so thrilled because my birthday present from the family is a new pair of GEC 807 ATS25.

Understand. :relaxed:

This is what happen when I tried it. https://www.head-fi.org/threads/eric-mcchanson-headphone-amp.718350/post-17778222 Gain is very low with 6as7 on Ultimate. https://www.head-fi.org/threads/eric-mcchanson-headphone-amp.718350/post-17762571

If you look back on my initial evaluation of Ultimate, I mention that the amp is prone to RF interference. When I put my iphone next to it to take pictures I can hear the interference clearly. Somehow strangely that all went away after a few months. Now I can put my phone next to it and there's...

The official name given by Eric for the 6as7 amp is gEm. Small and precious. :relaxed: There will be Mini gEm, Junior gEm or Super gEm. When talking to Eric about this amp, just mention gEm.

Eric ask me if I could tell whether a pentode or beam tetrode sound better. This is my reply to him. Hi Eric, These are the following Pentodes:- 6550 EL34 EL38 EL39 EL12 spez 6V6 6F6 EL84 These are the following Beam Tetrodes:- KT88 KT66 6L6 807 You cannot just determine whether Pentodes or...

Still early days with my russian Philips 807 but I find the tone very pleasing and crystal clear and with authority. My love for 807 has grown but it will take awhile before I compare it to EL39, EL38 and 6L6. These are the obvious candidates to compare it to. I will be getting another pair of...

I believe @rollinbr bought these. We will let him tell us if they work in Ultimate with 807 adapters. I think it should.

Is the Haltron russian? :relaxed: Can't believe the Philips 807 has USA on it but it is russian. What is happening to the world.

Never. Going to buy them all. :relaxed:

Oh damn looks like I need to get more 807

Enjoy Lory ! I miss my 3 months vacation. :relaxed:

Deleeh, there's Haltron 807 from Langrex. Don't buy all. Save a pair for me. https://www.ebay.com.au/itm/264074240411?

You are getting a lot tubes all of a sudden. Both my 807 are USA.

I was so eager to listen to the Philips 807, I didn't take a picture but here it is in Ultimate. The tubes are a bit shorter than the Radiotron 807 but size is no indication of sound quality. :) What is strange is that my Philips 807 has USA printed on the tube. I have seen Made in Great...
