All of the tube designs today come from the classic designs pioneered in the mid to late 1900's.
Within the past 10 years, many tube mics have been imported and flooding the market with products that have less than optimal components and quality control. The philosophy has been to make a product that works and at the least expensive price point. This has given the consumer products that sound harsh and hard compared to their elegant forefathers.
Some current production microphones have capsules, transformers, wires and capacitors that accentuate high frequencies and almost have a sizzle to them.
My philosophy is to use the best components possible to produce a microphone that has that "Vintage sound" and warmth. All of the mods that I do on tube microphones involve getting rid of the junk.
I use only high quality capacitors made by Axon, Solen, Black Gate, Rubycon, Elna and Nichicon.
The transformers are AMI, Cinemag, Jensen, and custom wound transformers made in the USA.
The capsules I use are ADK custom , Beeznees, Tim Campbell's CT12, Neumann reskinned, Peluso and Theirsh M7 capsules. I also have some
JJ Audio capsules.
The typical tube microphone mod consists of:
Replace all of the electrolytic capacitors in the power supply.
Rewire the microphone with Teflon coated, Silver coated copper wire.
Change the microphone circuit to a "classic" design circuit or a custom designed circuit.
Burn in the microphone for three days.
In addition we offer:
Transformer replacement
Capsule replacement
Grill mod
Body paint

The submini tube mods that I do, take your donor body and capsule and I make a custom circuit board to fit the mic and the tube. I supply and install the transformer. The capsule may be your stock capsule or optional capsule of your choice.
The mod can be a single pattern or multi pattern.
The submini tubes that I use are the 5703 and the 5840.
These tubes both have a big bottom end.
The 5703 is a single triode that is similar to the AC701. It has a nice low end that works well with the brite capsules. It is rich and full and has a nice midrange detail.
The 5840 is the tube that David Royer made famous with his MXL mods and his Mojave microphone. I use a different circuit and power supply. The tube sound is full and balanced. |
