The Heathkit/JBL 401-132 AS-48 speaker crossovers DEOIT (Desoldering, Electrolytic Oxidation Inhibitor Treatment) are an essential component for audiophiles and electronics enthusiasts seeking to restore or maintain the optimal performance of their vintage Heathkit or JBL AS-48 tweeter systems. These crossovers play a crucial role in dividing the audio signal into separate frequency bands for the woofer and tweeter, ensuring that each driver handles the appropriate sound range for superior sound quality.
The Heathkit/JBL 401-132 AS-48 speaker crossovers DEOIT are meticulously designed and manufactured to exacting standards. They are built with premium-grade components, including high-quality capacitors and inductors, to deliver precise frequency response and excellent signal handling. Each component is carefully selected and tested to ensure maximum reliability and longevity.
Over time, the electrolytic capacitors in these crossovers may degrade due to oxidation and other environmental factors, leading to a decline in audio performance. The DEOIT treatment addresses this issue by applying a special solution that inhibits further oxidation, restoring the capacitors to their original performance level. This not only improves the overall sound quality but also extends the life of the crossovers.
Installing the Heathkit/JBL 401-132 AS-48 speaker crossovers DEOIT is a straightforward process for those with some electronics knowledge and experience. The kit includes detailed instructions and all necessary components for successful installation. It is recommended that users desolder the old crossovers carefully to avoid damaging the speaker terminals or wiring.
For those who value the rich, clear sound of vintage Heathkit or JBL tweeter systems, the Heathkit/JBL 401-132 AS-48 speaker crossovers DEOIT are an indispensable investment. By restoring these components to their original performance level, you can enjoy the satisfying sound of your beloved audio system as it was meant to be heard.

Details:
They are being sold as-is. These are made for heath by Jbl. These are all vintage speaker components. Both crossovers work and the potentiates have been cleaned lubed with deoxit.
I think they are very similar to the le20. The dust caps have been pushed in but the tweeters sound great. They are used and the photographs represent over all current condition well. Included in this listing are 2 Heathkit 401-132 tweeters and AS-48 crossovers.
Both of the tweeters are working well.
