6) FREQUENTLY ASKED QUESTIONS
How do I hook up this thing?
- See Section 2, beginning on page 3.
Is the FX loop series or parallel? Active or passive?
- The FX loop is series, and is a buffered solid state type
Can I substitute different tube types?
- Although you can try 12AT7s, 12AU7s, 5751s without any harm, the
design is optimized for 12AX7s, and are therefore the only recommended
tube in the preamp positions.
- Please use only GZ34/5AR4 for the tube rectifier
- Please use only EL34s for power tubes. While other tubes might work,
knowledge, and mods might need be required. Please consult a qualified
technician for any mods.
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 amp, though!
I've read that the components used in this type of amplifier are really important. What is
inside my amplifier?
- 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, TAD Mustard
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.
