[Harp-L] UPDATE: The Mission Chicago Harp Amp

[Rick Davis <bluesharpamps@xxxxxxxxx>]

The new Mission Chicago Harp Amp is about to ship. To all of you who have
placed orders for the amp, Bruce Collins thanks you for your confidence and
patience. Your fantastic new harp amp will be arriving on your doorstep
soon.

Most vintage style combo amps, including the Mission Chicago and other
familiar harp amps, have two bolts on the top of the amp that secure the
chassis to the underside of the top of the cabinet. The transformers hang
off the side of the chassis, toward the front of the amp. Since the
production version of the Chicago amp uses massive transformers, Bruce
Collins decided weeks ago that the amp must have a brace to prevent the
torsional stress of the heavy transformers from acting upon the chassis
mounting points. This is particularly important for customers whose amps
will be shipped overseas. It can be a rough trip, and you don’t want your
amp in pieces when it arrives.

The fabricator has experienced delays. The stainless steel braces have been
cut but not yet bent. The braces will be finished in a few days and the amps
will begin to ship.

Here is another feature of the Mission Chicago amp that you should be aware
of: The eyelet board upon which the circuit is mounted is hand-fabricated
from a fiber-reinforced polymer sheet. Vintage tube amps used a composite
eyelet board that buckled when exposed to moisture. Anybody who has spent
time with old tube amps has seen these buckled circuit boards, and the
problems they cause such as noisy cracked solders. In fact, some makers of
expensive amps use un-dyed versions of the same old composite boards,
another invitation to future problems. The circuit boards in the Mission
Chicago amps are impervious to moisture and heat.
The Mission Chicago Amp is offered for only $999 for a limited time. 32
watts of outstanding vintage tone in a 34-pound package. Loud enough to do
battle at a blues jam without any PA support. Two Amps in One: It is
switchable from Fixed Bias to Cathode Biased. DEEP switch for fatter tone.
