fenrirlupus Posted November 3, 2009 Share Posted November 3, 2009 You can upgrade from a Ruby 2EB2C1B to an Accutronics model 8EB2C1B or an 8EB3C1B. (the first one has medium decay time, the second has long) they're short tank, like the ruby, but have 3 springs rather than 2, and sound closer to the 17" 2 spring tank that brianh was experimenting with... Naturally, it won't sound identical to a 17" tank, but it should beat the 2 spring ruby by a good measure... you can order here: http://www.accutronicsreverb.com/ordering.htm And if you INSIST upon using a 17" tank, the type 4 is what brianh was using, and the type 9 is the 3 spring 17" tank (it sounds fuller than the type 4 and the type 8... I want to put one in my hammond organ, which is currently using the stock type 4 tank) Link to comment Share on other sites More sharing options...

blackmore1514k Posted November 9, 2009 Share Posted November 9, 2009 One question regarding the reverb tank. I have checked accutronics and there are lots of different tanks with lots of different ohm ranges. ¿Are those you say the correct ones? Link to comment Share on other sites More sharing options...

brianh Posted November 10, 2009 Share Posted November 10, 2009 One question regarding the reverb tank. I have checked accutronics and there are lots of different tanks with lots of different ohm ranges. ¿Are those you say the correct ones? Blackmore' date=' the amp's output transformer requires a specific impedance/resistance. The tank in my VSr is a Ruby 2EB2C1B, with the impedance/resistance specs noted below for the other C1Bs: [img']http://i608.photobucket.com/albums/tt163/brianehuff/Rubytubechart2.jpg[/img] So you should use a tank with the same specs (i.e. the 9", 3-spring 8EB2C1B), otherwise you could blow up the OT. There may be some way of modifying another tank to bring it into spec, but that's over my head. In any case, check your tank's label and with a meter before ordering anything, the Chinese are notorious for inconsistent manufacturing practices....

jaydodge Posted November 11, 2009 Share Posted November 11, 2009 that ruby rrv-s2eb2c1b tank input is 600 Ohm / 56 Ohm and output is 2250 Ohm / 200 Ohm Link to comment Share on other sites More sharing options...
blackmore1514k Posted November 11, 2009 Share Posted November 11, 2009 Thanks very much Brianh, but acording to jaydodge, the 8EB2C1B has different specs than the stock one. Since I already bought one: 8EB2C1B Accutronics Reverb Can Input: 800 / 58 Output: 2575 / 200 Shall I use it or it is "dangerous"? Link to comment Share on other sites More sharing options...
brianh Posted November 11, 2009 Share Posted November 11, 2009 Well it's close, but probably not good for your OT. M-theory would know for sure, try PMing him. BTW, do you have an ohm meter? Link to comment Share on other sites More sharing options...
blackmore1514k Posted November 11, 2009 Share Posted November 11, 2009 Yes, I've got one. And I probably can try to check what the values are. I'm not an advanced user, but I'll try. Thanks again. Link to comment Share on other sites More sharing options...

It shouldn't have exactly the same specs though, considering the 3rd spring... Link to comment Share on other sites More sharing options...
blackmore1514k Posted November 18, 2009 Share Posted November 18, 2009 I finally tried the accutronics reverb. It gives a small omount of reverb. And turning the knob to max, it seems the total volumen goes a little down. As I haven't tried the stock one, I can't compare. But this one does not disturb the sound in any position. OT did not blow... yet. Link to comment Share on other sites More sharing options...
J.Ventura Posted November 27, 2009 Share Posted November 27, 2009 Hi. I'm Javier from Spain. (excuse my bad english) I've got an Epiphone Valve Senior since a few days and I'm very glad with it, except for the pressence pot (it does nothing) and... yes, the reverb. It sucks, literally. The behaviour of the stock reverb is exactly like you describe it, blackmore1514k (ta'nteráo? intento decir que la reverb tal como viene responde exactamente a tu descripición), but it really disturbs the sound from 3:00 on. So I don't think changing the reverb tank really fixes the problem, but tweaking some electronic components values should do... at least I hope so. I have no idea about the how, my electronic skills are very basic. Link to comment Share on other sites More sharing options...
TWANG Posted November 27, 2009 Share Posted November 27, 2009 I just want to know if changing the tank helped at all.. the hot rods reverb is pretty much useless.. if the vsr is the same.. it's either in the tank or the circuit. Link to comment Share on other sites More sharing options...
blackmore1514k Posted November 28, 2009 Share Posted November 28, 2009 TWANG, both things. I changed the reverb tank to the accutronics unit. This reverb has a short decay and that helps a little bit, and you can turn it to max and the sound does not come from the other side of the moon. But the circuit is also not very good. I asked Andy, from Valve Rat Amps, an specialist of tweaking small and cheap amps, about the reverb thing, he answered me that the Custom Blues has the same thing. Once you turn the knob to max, the volume goes down. He said that was easy to fix , just change a resistor (he did not say which one) and tons of good reverb appears. I plan to send him the head as soon as he gets one and tweaks it. Link to comment Share on other sites More sharing options...
TWANG Posted November 29, 2009 Share Posted November 29, 2009 ah. cool. the new tank on the valve senior seemed to make a difference. at least in the clip I heard the long flubby tail was gone.. but he had the reverb set so soft it was really hard to tell. No Pipeline there I told him, so maybe he'll do a clip with it cranked up a bit more. the vjr hot rod just is noisy and that's all. totally no good.

brianh Posted November 29, 2009 Share Posted November 29, 2009 I'm thinking it's the circuit too. I'd rather mod that and see how the stock tank sounds than buy a new tank only to have it snorked by the cheap circuitry. If it's only a resistor or two, then a new tank will only sound that much better... Link to comment Share on other sites More sharing options...
blackmore1514k Posted November 30, 2009 Share Posted November 30, 2009 I measured the rca jacks. The input shows 78 ohms. The output shows 210 ohms. The Accutronics shows 58 ohms aprox input and same 218 ohms output. Those are very different values of what we think. Or not? Link to comment Share on other sites More sharing options...
J.Ventura Posted December 16, 2009 Share Posted December 16, 2009 Hi. I've looked inside a Fender Deluxe 112 of my own to find what kind of reverb it contains. Casually it's an accutronics 8EB2C1B, so I've quickly changed them to see what happens. First I've measured the impedances: Accutronics 8EB2C1B (Fender): IN=59O / OUT=205O Ruby 2EB2C1B (Epiphone): IN=77O / OUT=220O After the change, the fender reverb sounds wors than before, but it's still acceptable. The Epi with the accutronics tank: the reverb sounds simply less than before, neither better nor worse: very little volume and very very short, and still the annoying behaviour of the pot at the last quarter remains the same, maybe a little better than before. Conclusion: it's not an improvement at all. Now I know that the solution is in the electronics. The tank I've used is quite old (about 12 years or so) but it sounded ok inside the fender.

TWANG Posted December 17, 2009 Share Posted December 17, 2009 Great post J.. I am still working on the hot rods other parts so I've been debating which tank to buy.. Now I wish I'd done reverb circuits before on vjs so I had a better starting place for the circuitry. TWANG Link to comment Share on other sites More sharing options...
Jamie1281734176 Posted March 7, 2010 Share Posted March 7, 2010 Has anyone upgraded the reverb on their BC30? I've been really wanting a Fender or Music Man lately and I think if I had some good reverb on my BC30 the GAS would be quieted. Link to comment Share on other sites More sharing options...
TWANG Posted March 11, 2010 Share Posted March 11, 2010 I'm convinced a tank might be better but just not much. It's got to be in the circuit. Rather than fix it at this point, I'd prefer to tear out the whole amp, and build a better one with digitalverb. Link to comment Share on other sites More sharing options...
