Custom Work
We service the entire line of Carver products which Carver corporation started producing
in 1978 to the end of their production line in 1996. We also service the entire original
line of Phase Linear products designed and built by Bob Carver. We also have 100% original
semi-conductor compliment for these products to ensure the original performance of the
audio signature.
Any audio product coming from the factory is produced to perform within the general
specifications of the engineer. This also, however, is done with a budget. Simple
modifications can be done to any existing piece of audio equipment to improve overall
sonic performance and stability. Our technicians have more than 60 years of experience
in engineering, modifying high-end audio components such as CITATION, KRELL, Mark
Levinson, Etc.
Carver Power Amplifier Modifications
Although the Carver line of amplifiers have more than enough power to drive any speaker.
Including speakers with difficult to drive, low impedance loads such as the well-known
Infinity Kappa series. We offer what would be
called the "Silver-Seven" upgrade and the Carver MK-IV. This upgrade for the Carver MK-IV
involves doubling up the output transistors for more efficient, low impedance drive, high
current steering ridges, polypropylene bypass capacitors in the signal path. Re-aligning
the triac firing angle and reducing the current limit circuit to allow maximum use of the
SOA in the devices used in the M-1.0t power amplifiers. The front end can also be modified
if the customer prefers the sound of the TFM series amplifiers, such as the TFM-55 and TFM-55X.
For further details, please feel free to give us a call about these modifications.
AL3 and the Original Carver Amazing Upgrades includes replacing
all the mylar capacitors with polypropylene capacitors. We also hand pick and match
values in all the electrolytic capacitors, and replace inductors in the low-pass
circuit of the crossovers for superior handling. The coils we use do not have the
tendency to collapse as the stock coils do. Our coils also have far superior
handling abilities. These changes will optimize the sound of any of the Carver
speakers without question, and the reliability also will have an extremely long life.
Likely up to 40 years, since electrolytics do have a lifespan.
