I have been focusing on gain tubes. I've been alternating the E80CC, E180CC, 6189 ... and I think the E180CC (Mullard/Philips) is the one with the best balance (quality vs. gain level). I liked the E80CC a lot but the gain increase was minimal compared to 12AU7. For the driver's tubes, I've been using ECC803S and several "esoteric" 12AX7 for a while, but I opted for the modest ECC83 Svetlana "Winged C" and a pair of Mullard CV4004 with unknown mileage too. IMO the most critical here are the gain tubes so I have not wasted much time here. As for the "Jiml/Gilmore" modification to raise the current to the plate of the driver tube, I think it was a good upgrade (thanks to both of you and Mwl for sharing it). If I'm not wrong, only Michael and I did the mod?

Has anyone continued to investigate something about preamp tubes? I still use the E180CC instead of the 12AU7.

Happy Birthday!!!

I forgot to comment that the German-Maestro also have identical Beyer housings and I would swear they also use the same drivers. I have several German_Maestro at home and they are very similar to their Beyer counterparts. German-Maestro webside

I think that Michael and I talked about that project at that time and decided to put our attention to the T2 mini. I don't remember how the two Sandwich prototypes ended. Maybe Congo or Matt can tell us something.

Umm.. here ? Ah no, sorry I´m mistake. it´s a Superlux.

In pharma-industry here in Europe are usually 10 to 11 years. In the US they are somewhat longer I think 20 in some cases. Far from this, the DT770 has been in production for more than 20 years so it would not surprise me if its design patent is expired or that Behringer and Beyer share shareholding. Something that catches my attention is that the new model is called "DT330/DT660" which would lead to suppose that it is a model "inferior" to the DT770.

jajajaja I settle for drugs and rock. Right now I don´t want sex ... it hurts too much ?

You need a Megatron ... and you know it.

I'm not sure. The same happens with the imitations of the "Beast". Although the driver is different, they are copying an industrial design. Another matter is that Beyer, after 1000 years of manufacturing the DT770, has granted or sold the patent.

Thanks guys!!! Craig, I'm glad you're fine. That finger already looks good!! Now I am fine. They have allowed me to return home today in the afternoon. For a moment I saw myself as one of Alien's characters. Since I have not been able to say goodbye to the year, now I will take the fucking medicines and start listening to some music at home. Iron: where were they from exactly?

The original is sold at a cheap enough price. Does Behringer want to compete with Beyer? On the other hand, how long do patents last?

At dawn from 31 to 1, I had an acute peritonitis ... so I left the year in the operating room ?

Happy new year!!

Vinyl...

As everyone knows, I have been using "fat boy" 6CA7 (Electro-Harmonix) since I set up the GG and I also used them in my Megatron for a while and I had no problems. In fact, I have several replacement quads. I haven't used them in my BH but I agree with you Michael that I think these fat ass girls ? "sound" better than the EL34. * From what I've read, the Electro Harmonix 6CA7s are true beam tetrode.

Supertramp "Breakfast in America" deluxe edition... IMO a masterpiece

A classic for Christmas holidays:

Happy Birthday

Happy Birthday!!!!!

Of course Here you can see how to restore these wonders
