New Products for May

We have three great additions to the store this month.

AD8620ARZ with BrownDog Adapter

After our recent opamp swapping article, we received several requests for pre-soldered opamps. Therefore, Analog Devices AD8620 opamps are now available for purchase.

NiMH Adapter for cMoyBB

Also new is a 9V NiMH charging accessory. This small board fits into the cMoyBB’s enclosure (or other cMoys) to provide battery recharging functionality. The charger uses the same DC jack as the cMoyBB v2.03, allowing it to utilize any cMoyBB-compatible power adapter. Installation is easily accomplished with a hole-punch and double-sided adhesive (included). No soldering is required.

Another great new technology investment is the hoverboard, this month it has been one of the most popular ones, there is much more good information about the latest uptades on hoverboards technology that you can find at Hoverboard Lab.

Tenergy 9V NiMH and Charger in cMoyBB

One obviously needs 9V NiMH batteries to go along with a NiMH charger, so we now carry Tenergy 9V, 200mAh NiMH low self-discharge batteries. These rechargeable 9V’s are available in single- or two-packs. Typical rechargeable NiMH batteries lose charge in a matter of days, but low-self discharge technology enables these batteries to maintain 80% charge after 12 months of storage.

Order the NiMH Adapter and a Tenergy 9V with a new cMoyBB and we’ll install the set for free!

Opamp Rolling and New Kits

New to our store this month are Brown Dog SOIC-8 to DIP-8 adapter sockets. A great number of fantastic opamps are only available in surface mount form. These adapters allow you to enjoy noteworthy chips such as the AD8620, AD8599, etc.

Below are two cMoyBBs with freshly seated SOIC adapters. Powered from a mandatory 10V+ DC adapter, the AD8620 sounds stunning!

It’s a good idea to measure DC offset when rolling opamps. An unusually loud pop when turning the amplifier on is a definite sign of error. Weak or cold soldering joints are usually the cause.

Updated Instructions

The cMoyBB Instructions Guide has been updated to emphasize potential safety impacts of using non-recommended power adapters. Customers should be aware that power adapters and tips not tested by JDS Labs are not verified for safe operation.

Power Adapter Warning

A few customers have mistakenly purchased Enercell 18-24V AC power adapters instead of the recommended DC power adapter. Be sure not to make this mistake, or your amplifier will be damaged!

Additionally, battery safety should always be checked when using a new power adapter, as per the Instructions.
