    RB300 arm and Audio Technica 007 cartridge, this feeds a home made head amp (based around the LT1028 Op -amp, better than my Audio South transformer, but that's another project). The preamp (valve) is a heavily modified Audion Premier. The speakers are a temporary pair of LNB 7s (a 70 litre transmission line design). Audio Note silver interconnects

    Maplin 50W amplifier module. These, along with most of Maplin's other audio kits, has now unfortunately been discontinued as part of Maplin's apparent move away from hobby electronics and into gadgetry. This circuit has, in one form or other, followed me though my DIY audio career.

    Mains transformers. We manufacture a limited range of C-core mains transformers, primarily for tube amplifiers. Our transformers are best used with bridge rectifier circuits (four diodes), but some transformers can also be used with full wave rectifier circuits. The hybrid power supply principle provides a bridge rectifier circuit using ...

[2110.05069] Efficient Training of Audio Transformers …

    https://arxiv.org/abs/2110.05069
    The great success of transformer-based models in natural language processing (NLP) has led to various attempts at adapting these architectures to other domains such as vision and audio. Recent work has shown that transformers can outperform Convolutional Neural Networks (CNNs) on vision and audio tasks. However, one of the main shortcomings of …

    Maplins sold an audio transformer. EI core with two bobbins. One for primary, and one for secondary. Two secondaries actually, but on that one secondary bobbin. It's odd to hear people say it wouldn't work. It was a 22-0 22-0 audio transformer, for their 50w amp boards. I'm actually selling one. Danbury made them.

SSAST: Self-Supervised Audio Spectrogram Transformer

    https://arxiv.org/abs/2110.09784
    Specifically, the Audio Spectrogram Transformer (AST) achieves state-of-the-art results on various audio classification benchmarks. However, pure Transformer models tend to require more training data compared to CNNs, and the success of the AST relies on supervised pretraining that requires a large amount of labeled data and a complex training ...

    Maplins Kits. « on: October 22, 2010, 08:15:56 AM ». Just a quick warning to anyone who uses Velleman/Maplin electronic kits: I spoke to a couple of staff members in my local Maplin today (Wrexham, if you're interested). I was looking for their electronics kits just to have a nose at, and one of the staff members told me they'd stopped doing ...
