Other designs using different power valves will have different requirements of course. Overdriving it will cause heavy distortion and is generally undesirable. Based on my experience with the Bugera 22 https: The 30W which I own is a beast but the 15W can hold its own in almost any setup. The input signal required for 1W output is about 4.

A brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. Minimum monthly payments are required.

They are PCB but the build quality is as good as it gets imho. Report item – opens in a new window or tab.

Search Media New Media. Therefore, revdrb we were to apply a constant audio voltage reerb to the coil, we would find that current through the coil would be less at high frequencies than at low frequencies, so the reverb sound would end up being ‘bass heavy’ and would sound very dull indeed! Cheap current source drivers: Interest will be charged to your account from the purchase date if the balance is not paid in full within 6 months.

Choosing the roll-off point for the input filter depends somewhat on taste. For the richest reverb sound, and for the lowest noise, the input transducer should be driven hard- almost to the point of saturation.


Any international shipping and import charges are paid in part to Pitney Bowes Inc. I need spring rverb. Low impedance reverb tanks seem to be persisting in valve amp design, which makes little sense since valves are not well suited to driving low impedance loads.

The DC resistance of the coil is negligible, except at very low frequencies which we don’t need- anything below about Hz is too revreb to be of use. This item will be shipped through the Global Shipping Program and includes international tracking.

Add to watch list. Jan 23, 8. The input transducer of a reverb tank is a coil of wire wound around an iron core. Reverbb traded in for a Carmen Ghia but I still would like to try a Maz 18 sometime. Please enter a valid ZIP Code. The ‘traditional’ driver is simply a small, conventional power stage.

The optimum value for both cathode resistors is: Seller assumes all responsibility for this listing.

Unfortunately valves are not well suited to this, but there are solutions.

But just a little. Unfortunately it doesn’t, as discussed, so at frequencies above and below 1kHz the reflected impedance to the valve will be higher and lower respectively, resulting in reduced power output. The Nighthawk is a little darker and dirtier. The Lightning has more tone tweaking capabilities: Unfortunately, the input coil is an inductor so its impedance rises linearly with frequency.

This is due both to its limited output power, a weak recovery stage and the fact that a 50k to k output transformer needs a very high primary inductance in order to produce low frequencies well like 50 Henrys! Most Active Authors Latest Reviews. The spring which has a magnetic pole on the end passes through an aperture in the transducer core. This amount is subject to change until you make payment. In this case the load is formed by the parallel combination of Ra and Rl, which are both 22k, making 11k in total ignoring the coil which is negligible and the output coupling capacitor which is large.
