Hallo Dave, to be honest I don't know what tell you, those are some of my amplifiers that I built during the last 2 years. I like to use only NOS tubes and high quality components. As you can see the S.E. tubes are 316A or 304TL or 808... Most of my amplifiers are S.E., I just built few P.P and one OTL. Photos in attach

Thank you Jim, I try to do my best! In attach another pair of mono amplifiers with GM70 tubes in SE driven by 2A3 and one amplifier made with only RCA UX.. tubes.
Congratulation. Very beautiful amplifiers. What schematic did you use for the amplifier with GM70? Is it working in Class A?
Tnx.
Nice covers, oil filters? =)Hallo Dave, to be honest I don't know what tell you, those are some of my amplifiers that I built during the last 2 years.

Hi Reegal
Are those 3B25 or 3B28 ? and all in positive bias ? I like separate the power supply and one for each tube, tube 810 805 808 812 809 826 in used

Wow..some amazing amps here!!
Guido, I really love your designs with the wood enclosures. They look like coming out of a steam punk future! breathtaking.
Tony, wonderful amps too! also love the second pic but the fourth catched my attention..is this a ATX case? brilliant idea!
One day, when I´m "grown up" I want to be in your guys league too!
In the meantime heres my humble approach at DIY hifi..I now it cannot compete with guidos and tonys projects but it is my first one and I´m still learning all the tricks and I´m quite proud of it nevertheless
JELabs Simple 45 design. I recently converted it to battery bias and I´m amazed at how much better the thing sounds without a cap at the cathode! Will try to substitute the 45´s cathode bypass electrolytic caps with MKP or similar soon. I bypassed the Electrolytic caps yesterday with small 0,22 polyprop´s prior to taking pictures....sadly it was too late allready to hear if it´makes a difference at all.
I tried to use only Oil/Paper and MKP caps in my build. OPT are Lundahl 5K to 5R.
Sound is veeery detailed but you forget to listen to details because it´s musicality demands attention to musik, not hifi ) .. I love my little amp!

Reegal - Your creations are truly original and pretty combinations of art and technology.

Hi Thafred
That is not ATX case, is a Xerox copy machine's power supply case, I got that for free, most case of my amp was from recycle of electronic equipment's case, got from surplus shop. or some of them were home made,You did very good job too keep going.second pic also battery bias for 5876 drive 809 SE. more pictures for you

I want to tank everyone for the nice comments about my amplifiers.
Here the smallest ultralinear 2+2W that I built few month ago.
Soon I will post the new SE with 211 tubes.
What is the big round thing uner the amp, power tranni?
Look forward to your 211.
