The ‘traditional’ driver is simply a small, conventional power stage. Jan 22, 2. Accutronics quote this figure as the Nominal Drive Current, which is the amount of rms current required for full drive. There are 3 items available. Add to watch list.

Unfortunately, the input coil is an inductor so its impedance rises linearly with frequency. No additional import charges at delivery! Lance Keltner has some amazing reevrb of Matchless Nighthawk and Spitfire, but he uses some pedals so they are not perfect description about amp cababilities. The Lightning has more tone tweaking capabilities: As more turns are added, the coupling of the EM field increases and the required current is reduced, so if there were turns we would need only 3.

In this circuit the heater voltage will also need elevating by more than 30V. Minimum monthly payments are required.

Please enter a valid ZIP Code. Therefore, if we were to apply a constant audio voltage signal 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! Discussion in ‘ Amps and Cabs ‘ started by AtmosphericJan 22, Obviously the drawback of this method is that we must use both triodes to obtain sufficient power since no OT is deverb.


The spring vibrations are then picked up in the opposite manner at the other end of the tank. Interest will be charged to your account from the purchase date if the balance is not paid in full within 6 months.

Skip to main content. So I can’t pull the trigger on anything until I get back. Includes 10 business days handling time after receipt of cleared payment.

No doubt this ‘brute force’ approach also compensates for the conventional, rather low-gain recovery stage.

More information on reverb tanks is also available at Rod Elliot’s site. The Nighthawk is a little darker and dirtier. Read more about the condition. For driving medium impedance tanks to ohms, say a more eeverb solution would be to use an SRPP.

The necessary filtering can be done at the input, and the input level can be limited to give the right nominal current for the actual tank being used.

The Lightning is considered the brighter think Vox reerb boost of the three 15 watt amps in the lineup. Jan 23, 5.

It was assumed that the coil presented an 8 ohm load or whatever more or less all the time, like a loudspeaker. See all condition definitions – opens in a new window or tab Select a valid country. When a current is passed through the coil the changing magnetic field exerts a tiny twisting force on the pole, which twists the spring too, of course. Learn more – opens in new window or tab. R1 simply allows the coupling capacitor to discharge if the tank is disconnected.

A simple circuit is shown [right], and is similar to many old designs.
