DLA-2A: Leveling Amplifier
A Studio Legend at Your Feet

The Doc Lloyd DLA-2A Leveling Amplifier is a meticulous recreation of an iconic studio compressor, now directly compatible with guitar and bass input signals. Less than 25% the size and cost of the original with 100% authentic tone. It took multiple years of dedication to make this ambitious goal a reality, but finally it is here.

The design includes Lundahl input/output transformers, 12AX7/12BH7 tubes, and a Kenetek T4B optical attenuator module. These components are expensive, but absolutely necessary to replicate this classic compressor's unsurpassed audio qualities. Two sidechain tubes are replaced with high voltage solid-state circuitry to significantly reduce size while leaving the original audio path fully intact. The line audio path is a precise match of the original schematic with a custom 275VDC low-noise internal power supply providing high voltage to the audio circuitry from a standard 12VDC input. This machine is the real deal. 

Typical studio compressors require line level signals from low impedance sources. The DLA-2A has the standard transformer balanced line input as well as a high impedance input with a balanced gain stage, providing direct compatibility with guitar and bass.

The compressed output signal is passed to a transformer balanced line output that can be connected to a mixing console or headphones as well as an instrument level output that can be connected to a pedalboard or amplifier.

DC power is applied to the tube heater filaments and does not generate 60 Hz hum, resulting in lower noise than the classic reference design.

Actually Cooling Pillow
Size: Queen (1 Count), Color: Original White (Cooling)
This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.
