Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.

A little bit of advice on old analogue equipment: controls like knobs and switches are mechanical devices in themselves and so require some specific care. These parts operate on metal (usually carbon) runners which can wear and corrode. Whenever working on a machine, we thoroughly clean and lubricate the controls, often 2 to 3 times over until clean. They can be difficult to successfully clean on some old equipment such as tube designs or even more recent machines that come from a smoky or moist environment (even proximity to major highways where there is a higher concentration of sulfur oxide and carbon oxides). These conditions can be more corrosive or staining to metal switch parts, making cleaning difficult but absolutely crucial. After returning a serviced unit to a customer, the cleaners remain active for about 2 weeks, so we recommend the controls be exercised occasionally to work in the cleaner. In general it is a good rule of thumb to exercise these controls at least once every 2 or 3 months just to keep the contact buffed.
