Tubes and Hybrids / Re: Can anyone identify this tube
« on: June 20, 2016, 11:01:22 PM »
Crap i dont have the right tubes, thanks. But since these are diodes could they be used for some kind of weird diode clipping distortion? Or is that something id have to mess with on my own

Tubes and Hybrids / Can anyone identify this tube
« on: June 20, 2016, 07:17:43 PM »
I ordered some tubes from the communist states of Russia the other day (no offense to my Russian friends!) They were supposed to be ecl8 tubes (for the low voltage tube amp on hackaday) but the ecl8 has 9 pins and these only have 7, im confused by this. They say "6X2П-EB" and are much shorter then most other tubes i have.

If you wanted two channels for two guitars to play on (like the peavey bandit 112 my guitar teacher uses) would you need two seperate preamps and power amps or can you just wire another input jack in parallel.

thanks! im sure ill figure out a way to test it. just didnt want to blow a tube or something

Tubes and Hybrids / 6v6 tube question.
« on: June 19, 2016, 12:17:13 PM »
If you took the power amp section of the fender champ amp (just the single 6v6 tube) and put guitar input directly to the 6v6 (eliminating the preamp) would it hurt the tube or just sound crappy? I was wondering if there was a way i could test just the power amp section first so i know it works when i test it with the preamp.

Tubes and Hybrids / Quick circuit question
« on: June 16, 2016, 09:05:44 AM »
Im building a tube preamp and i came across this symbol, was wondering if someone could tell me what it is. I see a 10k resister, is it just two 50uf caps drawn weird? Ive never seen it before and just wanted to make sure i know what it is before i build it

I gave up on this circuit. Know where i can find a circuit for a 2 watt power amp using 3904/3906 or will i have to buy more powerful trannies (in wich case ill go like 10-15 watts)

Haha i kind of figured as much. Im actually trying to find a simple transistor circuit to replace an lm386 i have. I need something with a little more power then the 386 puts out, mabey 2 watts. Is this achievable with 3904/3906 (all i have on hand) or will i have to bite the bullet and invest in some more powerful trannies.

Update: amplifier very quiet, transistors heating up, and distortion only at high volumes.

Im using the single transistor preamp with this 3 transistor amp circuit as a power amp. It works but its not good, im hearing radio signals, and alot of distortion. Whats wrong?

Thanks, ill try adding another diode. I will try connecting R1 to + just to see what happens. Thanks!

Amplifier Discussion / Quick question about this circuit
« on: June 12, 2016, 01:45:27 AM »
I built this amplifier circuit and i plan on using it for a (very) low power guitar power amplifier. It worked ok but there was some problems (bad quality at low volumes, buzzing, ect) wich was expected im pretty sure i can work those out.

My question is about the two diodes in series. I built it using one because that's all i had, how do those effect the circuit?

Tubes and Hybrids / Circuit for these tubes
« on: May 26, 2016, 10:35:58 AM »
Im looking for a circuit based on one of these tubes. Also if any of them are 12ax7 equivalent please tell me.

12B4A (i have two of these but only one of the rest on the list)
12CA5
12AL5
35C5
12BD6
12X4
12FX5
12BDK5
12BA7

Im looking for a preamp but if any of these can be used as a power tube i need one of those too. Im just a beginner and these are all i have access too at the momemt
