I´m using the same kind of socket (but I prefer bakelite). So far I have not had problems. You can solder them to the Pcb without problem (always when you have a powerful soldering iron, about 25 / 30W). I recommend that when you solder them to the plate, you have a valve inserted. This will keep everything aligned.

Good offer, all his discography for 53€. I'm starting to consider buying music in digital format.

Trimpot is for output current adjust. I used +/- 23Vdc but you can use until +/- 24Vdc. If you are thinking of using just one trafo for the four channels you will need a huge trafo. For a balanced configuration I preferred to use two PSU's and two GRLV's Edit: I'm sorry, I was confused. I still have trouble distinguishing the names of these two amplifiers

Happy Birthday!!!

Thanks Dr. Gilmore. It really is not that expensive either (an extra Opa and some more resistances). If it is as versatile as we want, what does it matter if something more expensive comes out? In addition, the unbal/bal works perfectly so it would be normal to have the buffer at the same level.

Buffer 2.0 is here:

I think that now it´s finished but I want to add a few resistor on the heaters filaments because I have 6.8vAC. Sometimes this happens to me with the Toroidy transformers. Front end tubes draw about 11,5mA. I was surprised that this amplifier has very little gain. On the other hand it makes up for it with a very pleasant and musical sound. I´m waiting a pair of E80CC for replacement the 6189.

Wooo Good discovery !!! Thank you It's like 80's glam or rock-metal... I´m thinking on Kiss, Van Halen....

Thanks ! I'm using other quartets and I've found two that work relatively well (8 EH 6AC7 "Platinum Matched Quad"). Offset is located at -8 and 14Vdc and low to -3 and 8Vdc. Now I feel more code to listen to the amp. I'm listening to it right now, It's totally silent and I like its sound although the sound is a bit "bass" for my taste. In the first and second stages I am using 6189 Sylvania JAN and ECC83 Svetlana W"C" . I'll leave a little time before going through those E80CC... what the hell? I'm going to buy them now ? About 21K resistor I think that you used a 50K in parallel to 21K . I think that it´s a good idea use parallel resistor here. This resistor is a 3w and runs to around 45º. Edit update: 47K parallel to 21K, now I have 302Vdc. Some pics ☺️My amplifier is not finished yet. I have not been able to order the wiring, finish the LEDs, etc... Megatron and my "Universal HV PSU" P.S. yes, I know, the appearance of all my amplifiers are the same. ? P.S 2º this amp runs HOT like hell

My megatron is already working. A couple of details: 1. HV 456Vdc and -452Vdc instead of 300Vdc I have 267Vdc, should I change the 21K resistor (I prefer something in parallel to it) or can I leave it running with 267Vdc? 2. Offset is between 40 and 29Vdc although the balance is about 5 and 7Vdc. With this offset I have not dared to listen to it. Should I change the output tubes? 3.Amp runs hot, very hot, very very hot ... no pets friend

Thanks for your replies.

Que mala leche!!!

Happy birthday Brent!!

Maybe you have right but for example I don´t want to spend time found obsolete parts or checking if my sand is a fake or not. One thing I have very clear is that I would never clone the box for example and presumably this is one of the most expensive components. I doubt that Dr. Gilmore wants to redesign the box. For other hand and following your way of thinking, for example I wouldn´t have a BH since the original has obsolete or hard to find components. Thanks to Dr. Gilmore and his latest revision I have an amplifier that otherwise would be impossible to do (for me, of course I suppose that it will be much easier for you). I do not know if I explain myself correctly and I do not want to offend anyone either. It's just my point of view. However, seeing that there are so many "buts" maybe a ver 2.0 is not a good idea.

I was thinking on a version with current components. Not a clone, rather an improved version. It's the same thing that happened with the BH. Why not with T2?

Really, there's no interest in a T2 "version 2.0" ?

Happy Birthday!!!

Happy Birthday!!!!!!!!!
