Do I need to use a matched and balanced phase inverter?
-
It is not necessary. Feel free to experiment with different tubes (of the same type) in your Chupacabra,
though!
I’ve read that the components used in this type of amplifier are really important. What is inside my Chupacabra?
-
We use a combination of parts custom-made for us to our specifications (power transformer, output
transformer, choke, high-temperature / low-ESR electrolytic capacitors) and those used in our British series
(1/2W carbon composition resistors, 1W carbon film resistors, Mallory 150M polyester film capacitors, high-
voltage silver mica capacitors, Belton tube sockets, and Alpha potentiometers, Cliff jacks). Finally, we
occasionally use NOS components from our vast surplus parts collection in locations they work well and
complement the voicing or enhance the performance of the amplifier.
I like to use rack-mounted multieffects units. What is the output level straight from the EFFECTS LOOP SEND jack, -10dB or
+4dB?
-
While not exact, -10dB is a better approximation than +4dB. The actual output level will depend on your
settings, particularly the volume controls. +4dB is usually reserved for recording/P.A. equipment with
balanced connections.
