Ceriatone Forum

Hi there

could anyone point me in the direction of the decupling caps ... not sure where they are on the layout ???
It s the s+m 50

cheers  :)

..

He he
cheers for the hint! dont worry my fingers aren't going any where near the internals of the amp. I am well aware of the dangers of ignorance in this area.Which is why  I'm taking my amp to a tech. I was just wonderin which they are on the layout. :)

Do you have any suggestions on where someone who is completely comfortable working with High voltage could learn all these terms?
I mean like a layout which identifies the special name that goes with each component!
It seems that if you ask a question that should be welcome in a builders forum, you get the " If you dont know, I aint telling " answers

90% of my day job I am exposed to much greater hazards than the innards of a tube amp. I've built 2 the paint by numbers way really and I know exactly how to work inside amp safely but that has nothing to do with the fact that I do not know where the coupling caps, snubbers, etc.

I really want to learn all this stuff but cant seem to get straight answers from anyone!

Thank


Todd

Hows the guy meant to learn unless he asks.

He could use the search bottom or google......................... :o

Why use search or google when we have a perfectly functional DISCUSSION FORUM right here. These forums SHOULD exist to help educate fellow owners and builders how to better understand the workings of their amps, not how to use the search function.

WOW are you always this helpful?

Seems that maybe if you put a disclaimer about high voltage in your profile you could save yourself a lot of useless post's

As the others stated, I come here to speak with the experienced guys about this stuff rather than google search and get a shitload of useless information.

If you think you are just to damn educated on this stuff to share than maybe you shouldnt even be here!

I honestly dont want to be rude here but this is unacceptable.

Do you own an amp building company and just dont want any more competition or what?

All the best :-X

Tells you what it does, not where they are!

Once I find out where they are I will try to answer your original question as intended!

Todd

If you follow the wires from pins 1 and 6 of both v1 and v2 you will arrive at the coupling caps. If you turn left at the junction you arrive at the plate (or anode) load resistor and right the coupling cap  ;)

They are used to block DC from getting through to the next gain stage or tone stack. The value of the coupling caps does have a bearing on the tone.

Can't recommend Merlin Blencowe's book highly enough.

Hey Tom, I would love to help you with this question... but I'm not 100% sure of the answer. If you are interested in learning the inner workings of a tube amplifier I would recommend " The tube amp Handbook" Buy Dave Hunter. It's a very good read. I'm at work now... but I will do some research tonight and try to get you an answer to you question. There is a ton of info to absorb about these amps and sometime's it can be overwhelming (IMHO) I am just scratching the surface of it myself... but it is very interesting and addicting.

Good luck. :)

I honestly think it would be nice if new forumites would take some time and effort and read through the posts in this forum and on the ampgarage. Why ask questions that have been answered a number of times by me or forumites??

This is my opinion I sincerely hope you can respect that.

It's cool man

Just think questions that are valid should be answered or at least point them in right direction.

Please respect my point of view

Peace.

I was staying out of this one just to keep the peace. But I went to eat dinner and come back to more of this. This is really BS. What the heck are these "karma points" and how do you give them to others? Seems like a rather arbitrary system to me.   ???

I can only speak for myself, but I'm probably very indictative of many that come here. Blues, you have to understand that I for one have been all though this forum and have found a lot of very good information, but I also have found  alot of confusing, conflicting, or just very indirect information. If you think it's not worth your time then don't say anything. And the (leathal danger) thing isn't going to cut it anymore. Make a general disclaimer and be done with it. I mean this in the most serious and respectful way I can convey this in words. I hope you take this the intent it is meant. :)

I wonder how many just give up and move on when they get banged like this. While I think a newcomer has the responsibility to be respectful and curteous to the members, they don't have the responsibility to read every word written since the start of the forum before they can ask a serious question. I would feel like I was asking someone to "kiss my ass" if I had that attitude.

Blues, I can tell you're a really smart guy and are a good source of correct information. I understand being busy and not having the time to answer every question. So, it would probably be best not to answer it at all. This is the only site for people specific to Ceriatone. It's not the most organized or even busy site. But, I can tell that when someone gets a kit and has an issue this is the first place they come. Having an attitude like "you fool, how dare you try to build a tube amplifier" just really sucks as a greeting.

I don't know if you know the webmaster very well, but a Disclaimer that's big and bold when you first enter the site would be great. Then we can all go about answering questions without feeling like we might be leading someone into danger. But really, if I give some directions to the store and they have to cross a busy street, am I really responsible if they hit by a car while doing it? I don't think so.

Point taken.

Wow! intresting. thanks very much for the info and book recomendations. I shall certainly check out Dave Hunter and Merlin Blencowe. peace and love  :D

Hello from another newbie.  I agree that part of due diligence for a new forum member here and elsewhere is to research posting histories.  It has saved me some questions, and it also pointed me in the direction of Merlin's book, which I purchased and am bit by bit learning from it.  My tube amp knowledge is very imbalanced...I know vintage tubes like few do but my knowledge of circuits and corresponding math equations has been much less.  Am learning bits and pieces from here and the ampgarage.  Fun!  A while back I did up a turret board for a BF Champ with some parts of my own choosing.  Now after I have spent some time here It'll be a blast to get back into it and apply what I've learned here and elsewhere. 

Somewhere in my basement lies a long-unused and nonworking condition Magnatone PA head with a pair of 6v6's, tube rec, and really big, rusty looking iron for a 6v6 amp.  So my dream project is to yank the trannies and do up a Martin/Dearmond type circuit for a pair of gorgeous sounding 40's vintage RT 6f6g's, but stick in an f/x loop, one of the most gorgeous sounding pentodes I've had the chance to listen to.  Have a lot of homework to do at the amp garage and personal reading...thanks to all who post helpful info here, it's nice.

Peace.
