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.

NOT DURABLE, LONG-LASTING, OR USEFUL
Color: A-Navy, Color: A-Navy
I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Albert” the Blue Bear! Safety (1-rating): Albert fell apart after 4-hours of use. 1. The ears were chewed off and I was only able to find one of them, which means my dog swallowed the other ear. Very big concern as it depends on how big your dog is to pass this object. The ear is about the size of 1.5-quarters. 2. The tail was almost chewed off entirely and was hanging on by a thread before I threw it out. 3. After the ears came off, the inside foam started to come out, which raised my concern for my dog’s saftey. 4. The entire body was soft and did not cause any harm to teeth, gums, paws, nose, etc. Durability (3-rating): 1. The ears and tail are the weakest parts of Albert as they can easily be chewed off. 2. The body is durable enough to sustain 4-hours of use, as I threw Albert out after the ears and tail were torn off within 4-hours. 3. The small squeaker inside Albert’s belly was broken after 15-minutes of use. Thank Goodness! 4. My next concern was how long the arms and legs would last; TBD! Squeaker (1-rating): 1. Small plastic squeaker, the size of a half-dollar, with a high pitched noise. Fatality (2-rating): 1. Albert was put to rest after 4-hours of use as I was concerned for the safety of my dog with continued use. 2. If Albert didn’t come with ears or a tail, I can only imagine how long he would’ve survived as the material seemed to be durable enough to withstand continued use. In conclusion, “Albert” the Blue Bear is not worth the money for a toy that falls apart after 4-hrs of use and with the concerns of safety. I was surprised that it was only 8-inches tall, next time I’ll confirm the size of the toy before I purchase the next one. About my dog “Cannoli” for comparison: Breed: Blue Healer / Lab mix Weight: 40-lbs Energy Level: High Age: 7-months Chew Rating: Aggressive

The dog won!
Color: A-Navy, Color: A-Navy
It’s not indestructible. Wonder if I can get a refund or another toy. It did last longer than most so I give them credit for that!

Almost good enough
Color: E-Navy+Purple
My dog chewy can rip through anything, even these. I do love the toys they’re great. They’re made with coconut on the inside, but could somebody please!, make a chew toy worthy of my dogs teeth, cause this ain’t it. But it is the strongest so far . I would recommend it. My doodle chewy short for Chewbacca is insane about chewing.

Could be more durable.
Color: A-Navy
It’s not as durable as I’d hoped. I’ve had to mend it. It’s cute, though, and my dog likes it. He’s an Aussie, so not great bite strength.

Cute but disappointing
Color: C-Navy+Oak, Color: C-Navy+Oak
One of my dogs love these however they are far from indestructible. Two days after giving the teddy to him, the tail of the teddy is off and there is a rip by one of the arms. They are very cute teddies but not for heavy chewers as they will only last a few days.
