what tubes do I need?

[beandip]

my gramps came down (the one that gave me the ES-125) and gave me his old mic and Gibson GA-30 amp. Well, all I know is the tube suck. So what would I need to get to make it sound nice and warm, but overdrive at a "loud" bedroom level? Im hoping to use this as a "studio" amp in my buddy's living room studio.

Well, tell us what tubes are in the amp. If you don't know, look at whats in there and write down the codes. We'll help suggest what current tubes work well for what types.

Since you got the amp for free, I assume, you need to get some high quality NOS tubes. No doubt. Make the most of it.

Re: what tubes do I need?

this is why I play a peavey transtube. lol. the big ones say RCA electron tube 6-04 and in a little stop sign design say 6v6 gt...and the little ones which seem to be made of metal say RCA electron tube 1-26 but also in a little stop sign shape it says 6sc7. Im so clueless.

What old mic is it? Condenser or dynamic? Brand? Yeah, I agree with Scott - since
it's free, spend a few buck on nice tubes. www.revolutionguitar.com
will hook you up with the best for the cheapest. If you hear any pops, crackles,
or abnormal hiss, it's likely that some of the filter caps need to be replaced.
Those old amps are so simple, you could probably locate the caps on the board, write down where they went, take them to a good electronics store, and come back and solder in the new ones. That's all you need to do to restore it to the same tone, or better, than it was when it was new. If you wanted to go further, a new Jensen speaker would make a world of difference.

Re: what tubes do I need?

I just did some reasearch and it says that the amp has 2-6v6, 1-5y3, 16sc7, 2-6sk7...all octal. whatever the crap that means.

Re: what tubes do I need?

there are alot of pops and a good about of hum. Im really nervous about working on amps, they bite back, guitars dont. lol. maybe I'll send it to one of you good fellas and let you figure it out. the mic, youve got me there too. looks like something you would play harmonica through, with a 20 foot cord, built in stand, and a 1/4 inch jack on the end. it says "Turner Dynamic Microphones. model no. 33D." now, if ya wanna talk guitars, thats a different story.

Just take it to a good amp tech you trust. Let him help you. But, for hte 6V6 power tubes, I hgihly recommend the Brimar's. www.kcanostubes.com

On the 5Y3 rectifier, a good JAN NOS one is pretty cheap, check the kca site listed above.

Also, you can probably find the other numbers there as well.

Re: what tubes do I need?

I like the new JJ 6V6's that Bob at Eurotube recently installed in my Fender DRRI. They gave my amp more warmth and increased the output.
JJ just started making 6V6 style tubes not too long ago, and they are well worth looking into. Bob also carries several NOS tubes such as Brimar's as well.
You may wish to contact Bob before you decide what type you want to buy, and for a second opinion.

Re: what tubes do I need?

if the amp works as is dont worry about replacing thoes expensive pre-amp octal tubes..... just look for a set of 6v6's (power tubes) you like there is some good choice and info at this page....

Re: what tubes do I need?

man, I dont know what that means. big ones, little ones? I know the big ones glow orange real quick, and one gets really hot really fast, but the rest dont. The amp is unplayable since you cant hear yourself over all the hiss, buzz, pops and static.

Re: what tubes do I need?

I would take it in to a good amp tech for a cap job before I plugged in again. I'd also have him put a 3 prong cord on it if it doesn't already have one. If the amp hasn't been used in a long time you can just about bet it's overdue. Let the tech retube it while he has it. You'll have a great little amp for what you'll have in it

Re: what tubes do I need?

the only guy around is a total jackass, I used to work for him, and for an amp repair there is a $50 bench fee, plus parts and labor. I quit after he found out I would charge a minimum of 25 bucks just to change somebody's strings. I refuse to take it to him.

Re: what tubes do I need?

At least take a look at your caps and check to see if any are swelled. If a cap blows you could ruin your amp.

Re: what tubes do I need?

I'm afraid to take this thing apart to look at anything. If this is ruined my ass is grass.

Re: what tubes do I need?

If you don't want to do anything to it yourself, and the only tech in town isn't someone you can trust, then you're going to have to send it to someone and have him work on it. Can you at least remove the amp-chassis from the cabinet yourself? You'll save on shipping costs if you can.

Re: what tubes do I need?

yeah, I just removed the chasis and took pics. Ive taken so many pictures of this amp you would think its a nekkie girl. lol.

Re: what tubes do I need?

I just pulled the tubes (I hope to God I didnt mess anything up), and the 3 big ones were all labled 6V6, 2 of the little metal black ones where 6SJ7, and the other metal black one was 6SC7.
