6bg6 tube amplifier schematic
I'm in the planning stage of my first tube amp push-pull , I'm trying to decide which output tubes to use. Can anyone make a comparison of these two tubes? I'm thinking triode s vs ultra-linear EL34s. I need about watts. Please vote!

EL34s or 807s chooses?
This is a great looking build. How did it come out finally? A couple questions. From the last photo it looks like you've added a ground from the board to the chassis, held down via one of the nuts holding the power transformer. Is this recommended? What is the additional white wire coming off the ground side of the speaker binding post?
I'm getting ready to build one of these and just want to learn from your experience. Surprisingly, that end bell that was paint shy is still waiting for a new coat. The powdercoater forgot which red he used he has quite a few , and he finally found it, but when he coated it, the finish bubbled up presumably from multiple layers so it had to be stripped and I think it's getting a new coat this week.
If you read through the DIYTube forum, and if I recall correctly as it has been quite some time since I touched this project, the amp benefits from grounding the board and negative terminals to the chassis. This is just my recollection though so hit up the boards and verify. Cheers and have fun with it! I loved the design. I wonder if it is to achieve the source schema.
Thanks for any information. The Ronaldo Silva. It came out Gorgeous, congrats! And thanks for the tip on the additional grounding that benefits this amp! Zynsonix Link.

The projects are all well documented and feature circuit boards for easy building.
The chassis was then powdercoated a nice cream color. The next task is to add some rubber grommets to the chassis where the wire from the transformers runs inside. This is to protect the wire from rubbing up against a potentially sharp edge on the hole and shorting to the chassis metal. It's an added precaution for the sake of safety.
The PCB and choke were then installed. The PCB was installed using standoffs, screws and lockwashers to prevent anything from coming loose down the line. The choke was installed using rubber washers underneath to damp any vibrations from making their way to the chassis, along with size 6 hardware.
The Edcors were wired into place. I've seen a number of members double up the 6. The extra 6. The power wiring and front switch was also wired up during this step. Directly after the fuse is a GE Thermistor wired on solder tabs the little black circle in the middle of the photo below.
A thermistor is a resistor which has a resistance that varies depending on temperature. In this case, the NTC thermistor is used for inrush-current limiting. A higher resistance is provided initially which prevents large currents right after turning the amp on. Once it has heated up, the resistance is much lower, allowing higher current flow. Many electronics contain high voltages that can kill, and mods, if performed improperly, can be a fire hazard. Please keep this in mind.

Anyway, since the amp is for personal use I don't need anything high power. So 20 - 30 watts will do. However the requirement is that the amp overloads nicely. I was thinking about a generic design using a grounded grid splitter and a choice of either 6V6, 6L6 or KT66 outputs.
Purpose of a clamp tube in an RF amplifier
It seems like a bare-essentials natural: a Pierce "aperiodic" oscillator driving a non-neutralized power amplifier for a multiband Morse code transmitter that requires just one coil and minimum adjustment. This page explores that topology, the Boosted Pierce Figure 1 , from its Great Depression beginnings through its canonization as a ubiquitous "glowbug" design that just won't go away. Fundamental to understanding the circuit is that it's an aperiodic-anode tri-tet oscillator that uses separate triode and screen-grid tetrode or pentode tubes. Multiple writers noted this effect. This circuit Figure 3 is the first publication of the triode-pentode Boosted Pierce transmitter—that is, a Pierce oscillator that drives a non-neutralized amplifier feeding an antenna. So Frank Jones can be considered to be the inventor of the Boosted Pierce—until we take a closer look at the January issue of Radio in which the circuit appears. As a result, the power-amplifier design in this very first Boosted Pierce implementation in effect includes Class A bias—not to protect against the underdrive later to become endemic in Boosted Pierce designs operating at higher frequencies, but rather in accordance with RCA's recommendations for proper application of the

The 1R5 or 1U6 can be substituted by rewiring the socket, with some loss of performance. Out of production, though old stock is occasionally available. Still made in China. Old stock American and European versions are very scarce and expensive.

I apologise, but, in my opinion, you are not right. I can defend the position. Write to me in PM, we will talk.
