Hey guys

Which type of replacement spring reverb tank would yield a surf reverb a-la Fender Tank?.

I'm looking to replace a wimpy tank in an EL-84 amp I have to get a more surf-"tank"-sounding verb. WOuld it be a 2,3 or 4spring? 9", 16"? long decay, medium or short?

I;m thinking of an Accutrinics, but there are so mant variations that I have no clue.

ANyone know about this stuff? Again, this is for an amp that already has a reverb tank in it but it's not very lush (it's a small tank, maybe 6 inches long) and I want to upgrade with the "best" replacement for a surf tone.

G, what kind of amp do you have? Does the spring you want to replace says anything on it? Is it an Accutronics? I'm asking cause you can't replace it with whatever. The replacement tank must have the same input and output impedance as the older one.

Every word is like an unecessary stain on silence and nothingness.

G, the best choice is to buy an outboard tank.....

About the Crate, I suggest an Accutronics tank. If you want a-la Fender tank choose the type 4 with long decay time. Visit Accutronics website and choose one with 150 Ohm input impedance. Be carefull to choose the right mounting plane....

Thanks guys

I have 63 Fender Tank. A blonde one with an NOS 6k6 in it and it sounds amazing. No competition with that.

I just bought this blonde Crate Palomino V33 112 ($399) and it's freekin fantastic! The verb, however is "normal", not bad, just "eh" for surf applications and since

I wanted a smaller 30W combo for practice, and this was it. It's a TOTAL Deville-killer, 100%. Better tone, MUCH better gain channel (actually usable for that Man or Astroman sound kinda overdriven tone), and it looks good with my blonde tank.

I'm upgrading the tubes and maybe the speaker on it, soI was considering replacing the generic 9" pan it with an Accutronics 16" pan to get a deeper drippier reverb that would suffice for practice and not have to haul my Tank around.

My other amps are a stock 62 blonde Bandmaster 212 and a 66 Showman w/ 115 Weber California in it. Heavy gear for weekly practices and too large for my Mustang's back seat

Not to be grumpy, but folks: pay attention to what he's asking. He HAS a tank. He knows what it sounds like and all that. He wants a reverb PAN recommendation to put in his new amp's onboard reverb circuit.

Maybe someone should edit the post title?

The standard pan used in BF/SF Fenders combo amps and the Fender outboard unit is the 2-spring Accutronics 4AB3C1B

http://www.accutronicsreverb.com/Type4.htm

The model 9AB3C1B is essentially the same thing as the model 4AB3C1B, but it has 3 long springs.

If you go to the link and look at the classification scheme, it's pretty obvious that you can't just throw in any ole pan. You never know...you might get lucky and it might work. However, you really need to know what the circuit is designed for. So, if you have a wimpy sounding pan in there now, like MelWaldorf said, you might want to send the brand and model number to Accutronics to see whether or not they make an equivalent pan with a longer delay or longer springs or whatever it is that will make the pan sound fuller. Then again, it might not be the tank at all. It could be that the circuit is wimpy and the pan is perfectly fine.

wouldn't a 16-inch pan sound "better" than the 9" pan I have, regardless of what's driving the pan?

Of course it would. I checked Palomino's circuit and you need a pan with 150 Ohm input impedance. Visit the link that is posted and check the type 4 pans (4 springs). Choose one with "long" decay time, type C connectors and in my opinion, 10K Ohm output impedance (you can ask the guys at Accutronics for this). And last, you must check how will you mount the pan!? Horizontal or vertical? This is critical to have the best results.
So a 4BC3C1"?" is what you want!
If you want Palomino's schematic PM and I'll send it to you via e-mail....
And why not send it to Accutronics and find you the best pan!
The reverb circuit is not the best, op-amps, but the 16" pan will sound better.

I wouldn't suggest the 4AB3C1B or C. The circuit will distort.... if the op-amp that drives the pan won't fry.
Kyle, he won't replace the pan from a tube reverb circuit. The 4AB has an 8 Ohm input impedance and the fender tank has a matching transformer between the tube and the pan. This transformer matches tube's impedance with the pan's impedance.

Kyle, I think it's morning there! Do you want a coffee?!
Yes, The 4AB3C1B or C is the recommended choice for any Fender Tank. But G will not replace a pan from a fender reverb unit....

I was only joking Kyle!
