You will soon find out, just as I did, that you need to update your iLok License Manager.

I have no idea why, but my PT11 rig just stopped working. PT11 wouldn't recognize my iLok that has worked just fine since 2014. Installing the latest iLok License Manager solved the problem. You need to go to

I record on a PC so I used the "Windows 64-bit Windows 7 or above" option shown below. My PC is never online, so I saved the file to a thumb drive and installed it on my PT11 machine.

First, it will ask you to "unZip" the installer file. Then you can perform the installation. The process doesn't take that long and it went smoothly. But, some sort of warning would have been nice!

I really can't stand all of this software license crap. I'm ditching the whole iLok thing as soon as possible. In fact, I recommend migrating back to hardware. That's what I'm doing.

Maybe if enough of us stop using iLok, these software idiots will pull their heads out of their asses.

FCC Spectrum Auction Kills 600 MHz Wireless Microphones

600 MHz Wireless Microphones

The Federal Communication Commission (FCC) held an auction to repurpose and sell portions of the national wireless spectrum. With the sale of UHF television channels 38 – 51, or 614 – 698 MHz, use of wireless microphone systems operating in the 600 MHz band will eventually not be permitted.

Gallien-Krueger 400RB Repair with Deoxit Fader Lube

My bass player still owns the same Gallien-Krueger 400RB bass amp he used back when we both lived in Los Angeles in 1989. It had been a while since he had used it last so it didn't work when he powered it on. The power came on, but with no sound at the output.

Everything looked good inside. It was super clean. But, the pots were very hard to turn. I suspected that the old pot grease had hardened and was getting between the wiper contact and the carbon element so I decided to clean all of the pots with Deoxit Fader Lube.

This stuff is amazing. It works so much better than the old can of Shack tuner cleaner I used in the past. A simple spray inside the element and shaft and then rotate back and forth a few times. Repeat the process until they feel new again.

When repairing any electronic equipment make sure to pay attention to what parts will have voltage potentials on them. Notice the two TO3 transistors at the upper right of the next image.

They are part of the power amplifier circuit. One transistor has about +65VDC on it. The other about -65VDC.  Let me tell you that +65V and -65V do not add up to 0V. Across those transistors is about 130VDC of silent killing potential. We must be very careful and respectful when working on electronic equipment.

Universal Audio M610 Tube Preamp

Inside The Universal Audio M610 Vacuum Tube Preamp

The M610 preamp is the same tube preamp used in the LA610,  LA610 MKII and 2-610. The preamp is made up of two separate feedback gain stages that are cascaded one after another.

The UA M610 Circuit

The first feedback gain stage can be adjusted with the "GAIN" switch on the upper left of the front panel. This switch selects a feedback resistor that can add or subtract gain to the circuit. The first tube in the circuit (left tube) is a 12AX7 dual triode.

The following feedback gain stage uses a 6072 (right tube). The 6072 is similar to the 12AT7 dual triode. Notice that the big knob says "LEVEL". This is because it acts like a volume knob and not a gain knob in the circuit.

The first feedback gain stage feeds the 250k ohm "LEVEL" potentiometer and you adjust the input level to the following 6072 feedback gain stage.

More info and measurements coming soon.
