Learn to Read an Electronics Schematic: Tube Version #1 

This helps a lot. My level of confusion, when looking at a schematic, just dropped significantly. Thank you very much!

YEAH ! Thank You! a few things were cleraed up. the transformer info and the wires lines. connected vs not.

I definitely found when I first started repairing old tube radios that having the tube data sheets for pin outs helps a ton, I remember looking at a all American 5 thinking why are these caps and resistors going back to pin 6 on a 35L6 that makes no sense?? Oh wait the data sheet says it’s unused, OH wait there’s a hidden black wire I didn’t see grounding it and they are using it as a ground point.

Technically, the 6V6 (and 6L6) are 'beam tetrodes'. Careful alignment of the control and screen grids and beam forming plates perform the same function as the suppressor grid in the true pentode.

Thanks Stephe. Very helpful material

Very cool content. I will need to view it a couple of times to fully ingest all of the data. Thank you Stephe

I use those downward triangles for ground when I'm drawing by hand only because it's easier than 3 lines and I'm lazy :P

Very good teacher. I enjoyed it a lot. Thank you.

Excellent basic breakdown

Elementary dear Skunkie ;) Oh, except that Euro solid box for inductor.. Somehow never registered that before The down triangle I use for midrail 'ground' in a single supply FX pedal ... The multi-lined down arrow is usually meant as chassis 'frame' ground like where the elec inlet grounds to metalwork - often drawn separately to prevent ground loops Ah, hold on, in the Euro way, lines crossing DON'T connect UNLESS there's a dot - that could be confusing if you're used to US schem's - (I was told NOT to use the lil arch-over, deprecated, but hey its good for clarity) Oh, over here I usually see zeners just drawn with ONE bent leg, pointing in, so'z not to confuse with Schottky's And folks DON'T confuse Internal Screen with tube's IC='Internal Connection', not meant to be connected to ANYTHING, right ?

Awesome stuff...thank you. I have saved this for future use. I appreciate you taking the time to go over these important things

Great video! Thank you!

Thank you! I've saved it for future reference and I'll probably watch it again so it can sink in better. I look forward to the next video!

Thanks, been waiting for this series.

Brilliant.

great info thank you!

Great stuff, very good of you to do this primer. My revelation moment was discovering the negative end of a polarised cap always goes to ground. Took me a while to figure that out!

Phenomenal information! This is explained so well! Thank you!

Hi Lady, you have a lot of knowledge about tube amps and electronics.I watched the series about reisong m50.Very well argumented. I have a Willsenton R8 and I'm waiting to hear your thoughts about it. I have a matched quad of nos russian tubes 6p3s-e which sounded wonderful on a 5881 amp.Electrically they work on Willsenton R8 but the question is If the electronic design of Willsenton is made to offer maximum performance with them. Congratulations for your chanel! My respect

Thank you for these basic tutorials! I am basically new to electronics and consider myself an audio file. I am interested in purchasing a Chinese tube amp and making modifications. In your opinion what is the least expensive option that will give me the best room filling sound and fairly tight base? It seems like the A12 is a model that you were able to get great results very affordably. I would love to see photographs of the final modifications on this amplifier. Also how would you set up a subwoofer with tube amplifier? Would you simply use an RCA splitter from the preamp? thank you again for your wonderful videos. The first video I watched everything was completely foreign and now that I have watched many of them I am starting to understand the jargon!

Very helpful, thanks so much :)
