cheddatom Posted June 15, 2009 Share Posted June 15, 2009 Isn't that expensive? Link to comment Share on other sites More sharing options...
Neil. Posted June 15, 2009 Share Posted June 15, 2009 no it's not so bad. The projects i've done so far have had such a low current draw, that even after they're done, i haven't had to replace the batteries yet. I do want to get a PSU, but i just don't have the money at the moment. I was looking at this one, which doesn;t seem too bad. However, i only get paid monthly, and this month i've a shit load of expenses, like muse tickets, flights, and materials for college. So maybe next month, but for the moment, the batteries are fine.

tomrulez Posted June 15, 2009 Share Posted June 15, 2009 Why not use a voltage coupler? The only downside I can see is that it eats batteries but once you get a PSU it will be fine. Link to comment Share on other sites More sharing options...
Neil. Posted June 15, 2009 Share Posted June 15, 2009 well once i get a psu, i'll use the 12v on it. i think i'll just build the VC till then. Link to comment Share on other sites More sharing options...

I've got a schematic for a VC if your interested, pretty sure there was in the Diefet thread though so you've probably already got it. Link to comment Share on other sites More sharing options...
Neil. Posted June 15, 2009 Share Posted June 15, 2009 yeah i got one, and i got a vero too. But, the vero isn't great, and really spread out. i'm almost positive i could redraw a smaller one. I'll forward you it if you like? Link to comment Share on other sites More sharing options...

Neil. Posted June 15, 2009 Share Posted June 15, 2009 ok, so, with the valvecaster on vero, i managed to get it to 15 x 10, which isn't exactly massive, but i guess it could be better. also, i just read about someone who tried it with a 6111 miniature and said it gave a bit more bass. This sounds really interesting, cos i find that some of my pedals tend to suck out the bass a lot. Link to comment Share on other sites More sharing options...
teej212 Posted June 15, 2009 Share Posted June 15, 2009 radio shack was selling 9v for 99cents!!! i bought 5, i would have gotten more, but i didnt have more on me Link to comment Share on other sites More sharing options...
Neil. Posted June 16, 2009 Share Posted June 16, 2009 ugh!!! pay day is so fucking slow to arrive. Anyway, when it does, i'm ordering parts for the VC build. I've my stripboard layout down to 11x9 holes, which is a pretty small size. I was looking back at the vid on yt of someones Valvecaster, made with an old stock GE 5751. apparently, the GE 5751 is a replacement for a 12AX7, but with 30% less gain, making it closer to a 12AT7 than a 12AX7. It's like, if the amount of gain you get from a 12AX7 is 100, then the 12AT7 is 60. The 5751's are 70. The vid is pretty much an ideal amount of gain imo, so, i'm thinking 12AT7 is a pretty good choice. I'll try both the AT and the AX, but the price of a 5751 is nearly double either an AT or an AX. Also, i was hoping to fit it into one of the hammond FF sized boxes, but it wont fit with a battery, so, it'll have to be one of the NEWER Big muff sized boxes. (about 1.5 times the size of a FF).

cheddatom Posted June 16, 2009 Share Posted June 16, 2009 Won't the valve suck your battery? I'd get a PSU and go for the smaller enclosure. Link to comment Share on other sites More sharing options...

If you're going to by a AT and an AX it'll cost the same as the 5751 so you may as well just get one of them! Link to comment Share on other sites More sharing options...
Neil. Posted June 16, 2009 Share Posted June 16, 2009 Won't the valve suck your battery? I'd get a PSU and go for the smaller enclosure. nah. It's a starved plate "engine" so, the current draw is something like 200 MICROamps. A FF, i believe, is somewhere close to 300microamps, so it should be grand. If you're going to by a AT and an AX it'll cost the same as the 5751 so you may as well just get one of them! this is true. However, i'd like to try an AX, and the AT sounds like it's a nice level of gain. Link to comment Share on other sites More sharing options...
Russell_A Posted June 16, 2009 Share Posted June 16, 2009 As promised... im making my Fuzz face clone.... 1 brick wall tho... should I get BC108C's or BC183C transistors? I don't mind "Harsh sounding fuzz" but I don't want it hissing like mad! and i don't want such an effect that all you can hear is a 'timid' fuzz... answers please... also to save you time... here are the Transistors... http://uk.farnell.com/jsp/search/productdetail.jsp?sku=9206817&_requestid=308081 http://uk.farnell.com/jsp/search/productdetail.jsp?sku=1017655&_requestid=310221 Thanks in advance!

Neil. Posted June 16, 2009 Share Posted June 16, 2009 have you checked out http://www.bitsbox.co.uk? SUPER cheap, and a great selection. What transistors are you looking for, and if bitsbox don't have it, i'll tell you the equivilants. Link to comment Share on other sites More sharing options...

What transistors are you looking for, and if bitsbox don't have it, i'll tell you the equivilants. well, i was looking for BC183C transistors the link is in one of my previous posts, and no, i didn't check bitsbox... its a rare (kind of) transistor, it has the most reasonable characteristics for a fuzz pedal though... very tweakable... but go ahead Trad3mark, you have better experience at making pedals than me so... shoot...

Neil. Posted June 16, 2009 Share Posted June 16, 2009 well.... you know that if you take a fuzz schematic, for example, you can totally interchange the transistors? So lets say I was building a Fuzz Face. afaik, that uses 2 x NPN's, right? Well, why not go onto somewhere like bitsbox (which i've used 4 times now, and i think tomrulz has used twice, both happy customers!) and order a varity of NPN's? From experience, i've tested a few in Fuzz pedals, with seriously mixed results. here's what i tried, just so you've an idea: NPN's: 2n3904 - Not too bad. Very reliable, and widely used in things like Fuzz Factories amongst others. Often can be a bit clippy, but gives consistent results 2N2222A - I prefer this to a 2n3904. You get a much smoother sound. Although at first i thought the volume was a bit lacking, i just realised my amp was turned down lol! i tried a bunch of PNP's though. I noticed more of a difference with those in the circuit, cos afaik, the NPN's are generally used for the boost parts of the Fuzz circuits. Are there PNP's in the Fuzz Face? oh, btw, i'm not trying to force bitsbox on you, but i had issues with farnell on two occasions, and i've had nothing but excellence with bitsbox, and i think tom's the same. Just giving advice from experience like. edit: btw, on bitsbox, they stock BC128B's. From the datasheets, they're not a million miles off eachother....

Hmmmmmm... nop, no PNP's in the Fuzz Face... here's the schematic im working off.... i'm not tempted to use a transistor that i cant find the data sheets for, let alone one that hasnt been included in a Fuzz face before, however, i will look at the 2N2222A in one or both spots in the Fuzz face, you cant go wrong! thanks for all the help... Indespensable! and chillax... they look cheap enough also! (Pssst.... if i dont find anything i like i can always go into school and "borrow" a few transistors ) Link to comment Share on other sites More sharing options...
