We have gathered here product models that Grant Fidelity have sold in the past, and have received factory schematics for service support purpose.
Please note: These factory schematics are AS-IS, i.e. as how they were provided by our supplier factories. Over time the products may have been modified or changed in design by the manufacturer without notice or without exact update to the schematics. Based on our past experience, most skilled tube amp service technician is able to service tube audio equipment based on these schematics provided by factory.
We, Grant Fidelity, CANNOT and DO NOT warrant the content of the schematics. If you do NOT agree with the above, please do NOT proceed to order the digital files. We do NOT accept PayPal dispute for ‘not as described’ after you receive the digital documents.
Each order allows for one product model and limit to one download only.
If a product model is not listed here, it means we do NOT have schematics for that model on file.
Some brand(s) may require a Proof of Purchase from authorized vendors before releasing their schematics. This policy is made by each manufacturer independently and we respect their request to support authorized vendors.
If you have purchased your item from a Grey Market vendor, i.e. online vendors based in China / Hong Kong, but not factories’ authorized reseller for ‘outside of China’ market, we are NOT authorized to release schematics to you. Please do NOT contact us if your item falls into this category.
