Hand-built tube audio equipment
Heated Cathode is a personal engineering project dedicated to classic tube amplifier designs and traditional construction methods.
A limited number of fully assembled amplifiers, kits, chassis and components may be supplied to enthusiasts who are genuinely interested in building or owning one of these designs.
Each amplifier is individually assembled and tested, using carefully selected components and meticulous construction. This is not mass-produced equipment, and availability may depend on current component stocks and workshop capacity.
What may be available
Depending on availability, I may be able to supply:
- A fully assembled and tested amplifier
- An amplifier kit with wiring, hardware and miscellaneous components
- A kit with or without tubes and transformers
- A drilled steel chassis, ready for assembly
- Printed circuit boards
- Printed circuit boards together with the required hardware
- Partial kits, wiring sets or other component combinations
Builders may prefer to obtain tubes or transformers locally to reduce shipping costs or to select particular brands. Kits can therefore be prepared in different configurations.
Request availability and a quotation
Because every amplifier or kit may have a different configuration, prices are provided individually.
The final quotation will depend on the selected model, the components included, current component costs and the delivery destination.
To request information, please write to me at:
Please include, where possible:
- The amplifier model or item you are interested in
- Whether you require an assembled amplifier, kit, chassis or components
- Whether tubes and transformers should be included
- Your country and delivery postcode
- Any particular requirements or questions
I will reply with current availability, a personal quotation, payment information and shipping details.
Shipping, VAT and import charges
Shipping costs will be calculated according to the destination, package size and weight.
Where applicable, the quotation will indicate VAT separately. Shipments outside the European Union may be subject to local import duties, taxes or customs charges, which are the responsibility of the recipient.
Payment
Payment can normally be made by:
- PayPal
- International bank transfer using IBAN
A PayPal account is not required to pay by credit or debit card through the PayPal platform.
Important safety notice
Tube amplifiers operate with potentially lethal voltages
By purchasing, assembling or using this equipment, you acknowledge the risks involved. Heated Cathode cannot accept responsibility for injury, damage or loss resulting from improper assembly, unsafe handling, incorrect use or unauthorised modifications.
Anyone assembling a kit must have appropriate experience in electronics, soldering, electrical safety and safe workshop practices.
This is not a beginner project.
