Re: Echopathetic: the worst, but so simple, analog delay aro

Hallo, the time cap is the 330pF. Try 200pF (two 100s in parallel), or 220 or, if you find the value, 180 pF.
It should cut down the wining but the repeats will be shorter but still useable as sjmple slap back echo.

Re: Echopathetic: the worst, but so simple, analog delay aro

Happy you like it mate, thank you for giving it a go. I am slowly working on a refined version. Do you use the true bypass layout, or the original not true bypass? The not true bypass version pops a little for the first couple of stomps; I had no probs for the true bypass version, but I use a split ...

Re: Fender Mini twin amp mods and some help needed

Sorry for the iron.... always a sad moment when they die. Bury it in the yard, next to the dog :lol: Before soldering I would try a simple jumper: if the schem is correct you should be able, jumpering a couple of components (have you got an alligator clip?), to do the trick. So, connect a speaker ca...

Re: Fender Mini twin amp mods and some help needed

Ok, so it's possible that the schem does not match the board (and maybe the amp). I would try tracing at least the small board before working on it. Nice thube conversion Thomas. But the 9v battery option would be lost. People are impressed when you plug this little thing in a proper cab, without ev...

Re: Fender Mini twin amp mods and some help needed

R10, not R12, based on the poster schem.

L1 seems out of power circuit.

Re: Fender Mini twin amp mods and some help needed

Hallo, probably jumpering L1 and R10 will be enough. Mono or stereo jack will not make a difference, granted you use a mono power cable for the external cab. Both tone circuits are good to me. You can download the duncan tone stack calculator to simulate the sound of a big muff tone stack and have a...

Re: Fender Mini twin amp mods and some help needed

Hallo, thank you for the schem, I got the mini deluxe that looks pretty similar. But the board is different: two sides with power amp on top with thru hole components and a smd pre on the bottom... mods will be difficult on mine. The "deluxe"is made of plastic. This is not so bad, since it was easy ...

Dirty fix for DOD Fx90 analog delay

I got one in good conditions for 50 Euros, it's a really nice analog delay... since you do a plug and unplug test (that I did not do in the shop :oops: ) and discover it sucks noticeably volume and trebles, even when bypassed. The schematic is online, it's not too difficult to locate the 470k resist...

Re: Self split push pull el84

Yes, I recycled everithing I could.
It was not bad, but I wanted to build something new.
No regrets, but I am lusting over a 25/30 2x6L6 version.... I may rebuild again the tonemeister, but I fear regrets and, mostly, I wonder if bigger transformers will fit :twisted:

Re: Self split push pull el84

This amp sounds very good and I use it for almost all the rehearsals and (few) gigs I did. I also have some lower and higher power options (vht sp6 and jet cith 20 head), but I use them sparingly right now; and I am building the board for an incoming 6L6 version right now. It will take months. Wile ...

I agree with Siro: coolaudio bbds are no good for full 9V supply.

Re: GENERIC BJT DRIVE

After some "test drives" I reduced the tone control to 50K (I just put a 100K resistor in parallel with the pot): stock the tone was effective only during half of his travel and the transition between bright and dark was too fast. Now it seems perfect.

Re: GENERIC BJT DRIVE

Nice explanation deafbutpicky, I think you got it right. Of course I did a lot of clippers options experiment before this choice: it gives nice distortion and still maintains good output volume and good dynamic control on gain. If you reverse one or two clippers pair, you will get more clipping but ...

GENERIC BJT DRIVE

Hallo, this is my first "ready to build effect project", so have mercy. Since I made a schematic and a layout (thanks to bancika for creating diylc and to storiboardist for showing me what it can do, even on perf) I think it belogs here. Since I started using only small (5 to 15 eatts) tube heads I ...

Re: Echopathetic: the worst, but so simple, analog delay aro

I received a request by a forum member to help him modify storiboardist's layout of the echopathetic for non true bypass. I can't (or don't know how to) send him pictures by pm... and via email too. This is a modified storyboardist's layout... so, dear story, if you don't like it, tell me and I will...

Re: Echopathetic: the worst, but so simple, analog delay aro

A small uppdate: after some tests with my band at rehearsals I remover the "pre enphasis" (the 2,2,n cap in series with the 4,7K resistor at the input). At full volume the sound was too shrill; now the bypassed sound is just a tiny little bit darker that straight in the amp. A great thank to storybo...

Re: ESR Graphic Fuzz [schematic]

Finally I made this one :horsey: Tried the first schemo, without input and output caps, but it did not work. Then tried the later schematic with the regular power rail, and it worked at first try; the soud is very similar to the YT videos. It's a funny pedal, but I think I won't box it right now, th...

Re: Echopathetic: the worst, but so simple, analog delay aro

Hallo, yesterday I was quite excited and just posted the soundclip. Today I am posting the last schematic (super simplified, but it's the one I recorded and, for me, it's quite decent), the perf layout (thank you bancika :hug: ). I found the perf layout quite difficult to do, maybe from the copper t...
