Valve Jr Hot Rod Reverb Fix?

[misadler]

Hey all,

Just bought my first Epi amp, a VJ Hot Rod. I like the amp, but the reverb really blows. I swapped an old 5751 into V2, and that made it better, but only because it made it more quiet. I know these are fairly new, but does anyone have a fix for it yet? I read in another post that swapping out the tank won't do any good if the circuit is bad. Don't want to spend much more, but if there is a fix, this amp would be pretty sweet.

Thanks,

I have one here and it definately is horrible reverb.

 

One guy swapped out the tank but then his clips didn't show much reverb at all.. so I suspect it made no difference.

And so far.. no hint of what might actually work in these things.

Thanks for the response, Twang. Be sure and let us know if you hear anything. BTW, What short tanks out there are an upgrade over the Ruby that comes stock.

I've forgotten the model but there's one that fits.. I think it's a bit longer and has three springs..

I'll see if I wrote it down somewhere..

Misadler, if the tank is a two-spring model, you might notice some improvement by switching to a 3-spring (type 8) model. Accutronics makes a variety of short and long spring models (long spring models are preferrable but won't fit a VJr.) Here's the link: http://www.accutronicsreverb.com/

 

But as some members have discovered, the tank isn't necessarily the culprit - it's the reverb circuit. There may be some info on how to improve the circuit at www.sewatt.com. If so, that would be a better approach than wasting $ on a new tank. Also, you'll need to be very careful which replacement tank to pick - the impedance must be close to the stock unit or you can blow your OT.

Brian,

Thanks for the info. I'll check out accutronics, but I'll def. check out sewatt first.
