Mosfet Booster modules are back in stock, after a short delay in manufacturing. The pc boards are red this time instead of green as shown here. We all know that red makes your tone hotter!

US Postage rates increased for 2018. Domestic postage (to the 50 US states) was increased by 50 cents for a small package with tracking.

However, the rates on all International packages containing merchandise have almost doubled, and are now a minimum of $14 US. The post office computers do not allow the desk clerks to accept small flat envelopes as anything other than packages. Sorry, but I do not have a solution yet to this rate increase for shipments outside the USA. I can still ship Internationally, but only at the new rate.

The rate and policy change by the US Postal Service has had a big impact on many businesses that ship small, light envelopes. Almost half of my orders are for International shipments and I suspect that the new postage rate will have a significant impact on this. I will continue to look for an alternate solution so that I can ship small envelopes Internationally at a lower price.

New Year’s Resolution… I must clean up the workbench!

A bucket-brigade-device (BBD) is not analog. It is a sampling circuit that takes small slices of the incoming voltage just like an analog-to-digital-converter (ADC), and the main difference between the two methods is in how the samples (slices) are stored. The BBD samples are stored as voltage levels on tiny capacitors in the BBD chip, while the digital system converts the voltage levels to a digital measurement and stores the binary word(s) in memory.

My web site was mentioned as a source in an article on Hackaday called:

Taking a Guitar Pedal From Concept Into Production

The $58 super jfet audio op amp. Mouser Part #: 513-MUSES03

And it is only a single, not a dual…

A new EDN article on low power and soft clipping was just published a few days ago, and lists one of my Lab Notebook articles as a reference:

Distortion pedal circuit features low power and soft clipping

The LSK489 jfet used in the article is a nice component, but very expensive. Not out of reach of a DIY builder, but not readily available and there are numerous less expensive jfets that could be used in the circuit with acceptable results.

Order assembled modules now, before the price goes up!

I had no intention of increasing the price of the modules, but I ordered some Jfet buffer modules this morning, and found that the factory had added a setup charge that almost doubles the price. Ouch!

I’m not sure if I can continue to offer pre-assembled modules at the new higher production cost, so I may have to look for a new assembler or discontinue them.

There are plenty of the Opamp and V-Doubler modules in stock, and lesser amounts of the others. The Jfet buffer module is out of stock but I will have it at the current price when the new order arrives in a couple of weeks.

I will keep the prices on all modules at the current amount through the end of 2017, or until the stock of each module runs out. Not too sure what will happen in the new year. The production cost increase does not apply to the ready-to-solder pc boards. It only applies to the pre-assembled modules.

Thanks for your interest. Best regards, Jack
