Amps for Idiots.

I'll have a copy of that too please.

A nice 'teaching' book is "Inside Tube Amps" by Dan Torres.

Another one is Tom Mitchell's "How to Service Your Own Tube Amp"

 

A guy that gets hammered a bit but I still like his books is Gerald Weber. He has 2 books out plus I think he still does the Vintage Guitar columns. You can learn a lot from them.

 

+1 on Gerald Weber

there's some really good info in those books for a beginer.

and the Aspen Pitman book too

 

Funk's "Tube Amp Workbook"

 

Which part of the discussion with your tech do you want to understand? (I mean, sure, all of it, but some focus would help). The books already mentioned do contain a wealth of good info, but some may also have a bit of misinformation and/or bits of opinion that are presented as fact. The problem, of course, is being able to tell the difference.

So I suppose my first suggestion would be to not rely on a single text (or web site, or tech), but to read as much as you can stand.

The next trick is to read some basic electronics texts (the Navy NEETS series is a good start) and then pore over some schematics for simple amps (like a Fender Champ) and see if you can apply the basic theory to figure out what's going on in the schematic.

The other suggestion is to find and play as many different styles and brands of amps as you can -- so when your tech says he's going to make yours more like a Brand X, you've got an idea what Brand X sounds like in your hands, not necessarily in your personal guitar hero's hands (who'd sound great thru anything anyhow )

 

Here's one of my favorite sources of information:

Ritchie Fliegler's AMPS! book is a pretty good overview/survey.

 

Is Tom Mitchell's book the one with the "Morley ad-like" b 6 w cartoon of the guy playing?

If it is, I just bought it. It is geared more for beginners, but I think they dropped the ball on not using enough drawings inside to explain important points.

Also, just browsing so far, was dissapointed to read in the "Heater filament" voltages section the statement "virtually all amps have AC heater filament voltages, and they should read at 6v. Set your meter for AC..." (paraphrased...I read it last night but don't have it here).

I own two Carvin amps (as do many folk) and these amps have two of their preamp tubes getting AC heater filament voltage, and 3 (on the MTS) inside a rectifier circuit that is supplying them with DC VOLTAGE...I know of other amps that also do.

That kind of sloppy writing will get some poor guy thinking his voltage there is off (because he is reading DC voltage on an AC setting) and could have been avoided by simply mentioning that a few amps DO have DC heater voltages, and maybe how to see on a schematic which you have.

Wrong information (or incomplete) in cases like this is worse than no information. This is the kind of thing that really bugs me. And the book seems to be a hybrid, giving too much info to a guy that is a new to amps or electronics, possibly letting them think armed with the book they can check voltages, etc.

Seems irresponsible.

 

Hello SBB,

I understand your concerns and agree. There are holes in most books regarding this subject. It is good that you are able to point out the incomplete information.

There are statements in almost every book that I have read on this subject that I have also questioned or have found to be 'half-truths'. There is no absolute bible.

The two books that I pointed out earlier are interesting for stimulating thought and discussion for those who are new to the subject, even though there may be some 'rubs'.

A series of very nice books about Basic Electronics, five volumes, (Van Valkenburgh, Nooger & Neville) are very accurate (circa 1955), but they are not specific to Guitar/Bass amps but have a lot of info about tube aplication/understanding.

Another Guitar Amp related book that I like is Dave Funk's Tube Amp Wookbook.

 

Alll of the above, plus The Tube Amp Book by Aspen Pitman, offer valuable information. None is completely comprehensive and all have some information overlap.

Read as many as possible. And yes, basic electronics is very important and something rarely covered in these books.

 

the jack darr book is good (and free too)

 

Amps for Idiots. Think we got a winner for next years shop tee back script....

 

Just to clarify, your MTS uses DC on just two tubes, V1 & V2. The Legacy runs V1, V2 & V3 on DC, the Vintage series amps run just V1 & V2 on DC like the MTS.

 

Aspen Pitman's book is more of a cheerleading manual for guitar amps, nice but not much nuts and bolts.

Weber's books have some opinion stated as fact and aren't too in depth but are an easy read.

Torre's book is OK, but some of the details are wrong or unhelpful.

Dave Funk's book is a very good resource, although it only covers Fender amps. It's readable, mostly understandable for a beginner and goes far enough to satisfy a non-novice. No real downside I can see, except it's harder to find (check Thunderfunk website).

Kevin O'Connors "The Ultimate Tone" I-IV have a LOT of detail, but are a bit over my head.

A good (older) electronics text is a great idea-again not definitive (mine gets a bit confused about some things, obviously written after solid state had mostly taken over) but very helpful and often written for beginners. I wish I'd kept my Radio Designer's Handbook!

 

OTM,

Yes, very good material regarding the Jack Darr Book. He also co-wrote some others for HWS. These books are not easy to come by.
