PunkRockerLuke Posted January 4, 2008 Report Share Posted January 4, 2008 My brother gave me an 8" car speaker for christmas. What kind of amp could I build using the speaker????? Quote Link to comment Share on other sites More sharing options...

aidlook Posted January 5, 2008 Report Share Posted January 5, 2008 I think you have a lot of reading to do. If you ask what kind of amp you could build based on a speaker you have, there is some fundamentals that are clearly missing. Do a couple of weeks hard studying and you'll probably find your answer, google is your friend. There are also better forums than this one for tube-amp related questions.

Geo Posted January 9, 2008 Report Share Posted January 9, 2008 Would I be able to make an amp using this?????? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...s_promot_widget Probably not. That's a PCB for a preamp, which will get you almost no sound in a speaker without a poweramp. Go here for tube amp stuff. http://www.el34world.com/Forum/yabb2/YaBB.pl If you want to build a tube amp, the usual suggestion is to buy a kit from a supplier and build something simple like a tweed Fender champ, like this. http://www.schematicheaven.com/fenderamps/...p_5f1_schem.pdf That's about as simple as a tube amp gets. There, I gave you some links, you gots to do the rest yourself. Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted January 9, 2008 Author Report Share Posted January 9, 2008 I think I could find a car audio power amp. But then again a car audio power amp probably wont do crap for me in a guitar amp. besides I dont think car power amps use tubes. I'm going to just take my time. I really dont want this project to be the death of me so I'm going to take my time and research everything I think might be useful. Quote Link to comment Share on other sites More sharing options...
aidlook Posted January 9, 2008 Report Share Posted January 9, 2008 Ok, from you replies it seems like there is really some really really basic understanding of guitar amps that is lacking. Start by just reading up on what guitar amps are, what they do, and what the different types do. It's a pretty good idea to know exactly what it is you're building if you want to build something.

PunkRockerLuke Posted January 14, 2008 Author Report Share Posted January 14, 2008 (edited) Well aidlook, you seem to be right that I lack understanding of amps. I understand solid state amps somewhat well but I do not get tube amps at all so I've decided to build a solid state amp instead and save the tube amp for R&D. Now for a new question. I still have my little gem mini practice amp project that I could use for the 10" speaker. What are some circuits for tone, treble, and reverb that I could put in the amp?

PunkRockerLuke Posted January 15, 2008 Author Report Share Posted January 15, 2008 (edited) Ok I have a section of my design planned out. Now I need you guy's knowledge on if this section would work. My idea for this first part is to connect the little gem : http://www.runoffgroove.com/littlegem.html to the stage center reverb from general guitar gadgets: http://www.generalguitargadgets.com/index....3&Itemid=26 Would this work and how could I connect them? My guess for connecting them is to connect the wires to the SPST switch. Edited January 15, 2008 by PunkRockerLuke Quote Link to comment Share on other sites More sharing options...
pauseflash Posted January 17, 2008 Report Share Posted January 17, 2008 well, you are talking about trying to learn about amps. I'd really sit down and work a breadborad of the mini gem. Change out the voltage divider and tone caps to see how different things effect the tone. It'll be a huge thing that will help you later down the road. The reverb would work fine. being a single stage solid state amp you'd just run the amps output straight into it's output. Almost like a pedal. In a single stage solid state amp, there is no effects loop to worry about. As to where to hook it up, I would just run it off a DPDT switch for True bypassing. But yeah... The more you mess around with the basics, the better off you'll be later. I think you'd be suprised how much little 10 cent changes effect tone. Then you'll start ripping apart nice amps trying to make them sound "better". good luck! Quote Link to comment Share on other sites More sharing options...

weezerboy Posted January 18, 2008 Report Share Posted January 18, 2008 as far as i know you need a reverb tank for the stage center reverb. theres a bunch of tone-stack schematics allover aron nelsons, rg keen etc websites. Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted January 18, 2008 Author Report Share Posted January 18, 2008 yeah I know I'm saving up the $30 or so I'll be paying but who the hell said this was cheap? Quote Link to comment Share on other sites More sharing options...
Thoughtless 7 Posted January 18, 2008 Report Share Posted January 18, 2008 I've just priced up parts for a Fender Delxue (5e3) and its going to cost ~£250/$500. Might not be cheaper but its very entertaining to built through it! Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted January 18, 2008 Author Report Share Posted January 18, 2008 Which TLO74 is the one I need? A DIP or SMD? Quote Link to comment Share on other sites More sharing options...

My guess for connecting them is to connect the wires to the SPST switch. I would put the reverb first in the chain as with a stompbox, and wire it with true bypass, 3pdt toggle switches are easier to find and not as expensive as the foot switches and could be used since you won't be stomping on it. Then ditch the output jack of the reverb and the input jack on the amp, connect the leads going to the output jack on the reverb to where the input jack would be wired on the amp.

curtisa Posted January 19, 2008 Report Share Posted January 19, 2008 Which TLO74 is the one I need? A DIP or SMD? You want the DIP version, that's what the PCB is designed to take. DIP = Dual In-line Package SMD = Surface Mount Device Quote Link to comment Share on other sites More sharing options...

PunkRockerLuke Posted January 20, 2008 Author Report Share Posted January 20, 2008 OK I plan on using a transformer to power the amp. My idea was to use a old toy train transformer but it only puts out 12 VDC and 9 X 3 is 27 so I'd need 27 VDC power right? Or have I gotten something wrong? Quote Link to comment Share on other sites More sharing options...
curtisa Posted January 20, 2008 Report Share Posted January 20, 2008 "9x3"? Sorry, don't know what you mean by "3". The 12V plugpack will probably work fine with the circuits as-is, even with 3V more than you need. Quote Link to comment Share on other sites More sharing options...
PunkRockerLuke Posted January 20, 2008 Author Report Share Posted January 20, 2008 (edited) I meant 9 times 3 since the Stage Center Reverb has two 9V batteries needed and the Little Gem has one 9V battery so that makes a total voltage of 27.

aidlook Posted January 21, 2008 Report Share Posted January 21, 2008 No.. You still need 18V in the reverb (assuming the batteries are in serial) and 9 V for the amp, unless you want to run them on batteries the easiest way would probably be to run them with two separate transformers. Read up on electronics at a site like allaboutcircuits.com and you'll be able to understand most of what you build a lot better, and it'll most likely be more rewarding to know what you're doing as well.

PunkRockerLuke Posted January 23, 2008 Author Report Share Posted January 23, 2008 Ok the capacitors are all mylar/poly except for the 220 picofarad which should be ceramic. Am I correct on this? Quote Link to comment Share on other sites More sharing options...
