Amplifier Discussion / line 6 30W V's 75W
September 17, 2006, 02:24:06 AM
Hey, I have played a mates line 6, spider 2, 75W amp...it sounded awsome

There is a 30W one on ebay I want

Will the 30W sound quality be the same as the 75W sound quality at bedroom pratcice volume?

Thanks

Hmm do they have many problems with these amps?

im still thinking of getting it...hmm
#3
Yea thanks fellas, Im in Australia The guy has it on ebay for $510 and the RRP is $800

I think i will just buy a new one, probbaly not worth the risk.

Thanks mate, im a bit unsure about buying one 2nd hand, if it stuffs up i have no waranty, they would be pretty pricey to fix?

Hey, im looking at a 2nd hand Line 6 Spider II (2) 112 Guitar Amp Combo, 75 W I think.

Has anybody had any experiance with these?

Ive played one once and it sounded pretty good, I only need it for pratice.

I dont have time to build an amp atm.

Can you still run effects peadles through these amps? i think they are all digital???? would that make any diffrence?

Thanks, I still cant get it to work, when i turn it on there is a small buzzing sound, and no signal from the guitar is getting through.

You connect the negative terminal of the battery to the ground?

Ok, maybe nobody understood me, ill attach a pik.

I have read that you connect the tip to the input, the sleve to ground and ring to the negative battery terminal, how do you know what is what? one terminal is slightly golden (3) what one is this?

Do you connect the negative battery lead to ground?

I have no idea about the pot, is what i have done in the pik wrong?? im guessing it is because my pedal isnt working.

ok, thanks.

The two outside pins on the potentiometers, are these the same?

and for the linear potentiometers...these have 6 pins, what do i do here? solder the matching pins togeather then go about it normaly?

Thanks, sorry about the stupid questions.

Hmm just did a google search and the transistors i got sold were 2n5485

http://www.fairchildsemi.com/ds/2N/2N5485.pdf#search='2n5485'

Would these still be as good as the j201?

Yep righto,

Just went to the shop, got all resistors, potentimeters and the dude gave me some transistors which are heaps close to the j201's he seemed to know what he was talking about.

Ill get the caps and trimers tomrow....hopefully this thing works.

Righto, thanks, do you think the potentiameters for gain, volume etc will work?

1) Yes. They are "trimmer" -type variable resistors used to fine tune the bias of gain stages.
2) Yes.
3) IMO, you should avoid electrolytics and tantalums as much as you can: They are unreliable on a long term. Ceramic capacitors will introduce a little distortion. There´s a lot of other options but they tend to cost a little more. I would mind about the proper voltage rating and physical size first then pay attention to details like tone of the capacitor.
4) Yes, it´s a FET-transistor. http://www.fairchildsemi.com/ds/J2%2FJ201.pdf
5) Yes. They are "potentiometer" -type variable resistors. Pay attention to their "tapering". Some have a linear resistance, some logarithmical (audio).

Righto, thanks for your help,

So I would need logarithmical potentiometers?
