GEN-300B Update #5: Coming Together
Hi everyone, We wanted to share another quick update regarding the production progress of the GEN 300B/2A3 amps. Our custom parts were shipped out to us last Friday. Transit will take approximately one month, and at the moment, our estimated shipping window is early June. We have also secured a manufacturer for the glass cover. We expect to receive the first sample by the end of June, around the time of T.H. E. Show SoCal. 3D Render of the Glass Cover Thank you again for all

GEN-300B Update #4: Processing
Everything is moving along nicely on our end: initial QC rounds are complete, and key components are now in production. At the same time, we wanted to share a few updates on the upgrade options as things continue to take shape. Glass Protector We’re still in the process of sourcing the glass casing. We initially reached out to several U.S. manufacturers, but low-volume production costs came in significantly higher than expected. As a result, we’re now working with alternative

About International Shipping
Hi everyone, hope you’re having a good weekend. We’ve received a number of questions regarding our internal shipping rate, so we wanted to share a quick clarification here. At the moment, we’re not able to provide an exact shipping quote for international orders, as final costs will also depend on different location. The amplifier weighs just under 40 lbs (18 kg) , which contributes to the variability in final shipping cost. To keep things moving, we are currently applying a

GEN-300B Update #3: Power Matters — Continuing to Push the Budget Limits
Hi everyone, We’ve begun implementing Caddock resistors in the power section of our Gen series amplifiers. We believe the power stage to be one of the core elements of a tube amplifier. Below is a brief look at our approach to Caddock resistors . Traditional Power Resistors Most traditional power resistors used in tube amplifiers fall into a few categories: Wirewound Formed by winding resistive wire Inherently inductive Large thermal mass Under dynamic load, they don’t behave

GEN-300B Development Update – Pushing the Design Further
Hello everyone, Bruce here from Layer Audio Design. Over the past week we reviewed several aspects of the GEN-300B and decided to further refine a few details before moving into the next stage of production. Because this amplifier is offered at a very accessible price point, we also felt it was important to push the design as far as possible within this budget and continue upgrading several elements where it matters most .
