| Power Tube Matching From that article, it looks like he is saying that the top, 2 digit, number on a tube box will be between 32 to 42. @tonydennison No that is not what he is saying. If you read the very last paragraph Roger wrote Bias is matched within 4% and Gm... | |
| Power Tube Matching Roger Modjeski designed his own proprietary computer tube testers to ensure appropriate matching of power and signal tubes. So here is a tutorial from a very knowledgeable amplifier designer and tube expert: https://www.ramtubes.com/article-5 that... | |

| A Black Box to Solve Everything @bdp24 Yes a preamp and a reasonably easy kit to build. Nelson is brilliant with solid state devices and while Ralph and Roger are/were known for their brilliance with tubes, Ralph has now demonstrated he can manufacture a solid state amp with sim... | |
| A Black Box to Solve Everything Nelson Pass's DIY Nutube preamp kit allows for adjustment of distortion. Here is a description from the design document: "The attraction of the Nutube in an audio circuit is the Triode character, allowing adjustment of the distortion by operating... | |
| Budget preamp with quality volume control Music First Audio is a subsidiary of Stevens & Billington which is why their products use those transformers in their design. When S&B used to let people use the transformers for DIY and OEM John Chapman at Bent Audio built a very nice pas... | |
| Atma-Sphere Class D… Amazing I love my MA-1 amps, and have learned to live with them, using NOS tubes, turn them off after listening, and so on. The best advice I got from Ralph was to match them with optimal speakers. I would say that advice applies to any amplifier. | |

| Tube amps - what 3 things… I agree with the previous comment on transformers being the most important component. Until they aren't. Tube amplifiers with output transformers, regardless of how good they are wound are not as transparent as their OTL or direct drive counter... | |
| Decware and “The List” Not sure why, but it appears the OP edited their original post from a longer story about being on the list and having to cancel their order to this two word version. | |
| Tube amps - what 3 things… I have an allnic in the house now and need to adjust bias every time I switch it on - is this normal? @mpoll1 No it is not. Are you allowing the amp to warm up for 15 minutes or so before checking bias? Bias should be pretty stable once it is s... | |
