The Tubedrve utilizes 2 pentode tubes per channel, for a total of 4 tubes per module. The first one is an EF86 and the second one a 6AS6. The 6AS6 tubes is overdriven, providing the distortion.\u003c\/p\u003e\r\n\u003cp\u003eThe 6AS6 can be switched from pentode to triode operation. Triode mode provides a smoother type of overdrive with more ‘even harmonics’. Pentode mode gives an aggressive distortion with more ‘odd harmonics’. Switchable bypass and a mix knob for parallel processing provide pro audio requirements. The two channels are controlled independently from one another.\u003c\/p\u003e\r\n\u003cp\u003eThe module can be controlled with an input or ‘drive’ level, controlling the audio signal going to the tubes. A bias control sets the operating point for the distortion tube, allowing the user to control the bias current. With high and low settings this introduces asymmetrical waveform clipping, providing a more aggressive sound.\u003c\/p\u003e\r\n\u003cp\u003eA boost switch provides 15 dB of extra gain, for extra overdriven tones. An output level control controls the level coming from the tubes. A simplified overview of how the Tubedrve works can be found in the manual at the bottom of this page.\u003c\/p\u003e\r\n\u003cp\u003eThe front panel is made of black anodized aluminum providing a long and lasting finish.\u003c\/p\u003e\r\n\u003ch3 id=\"toc_0\"\u003ePARALLEL MIXING\u003c\/h3\u003e\r\n\u003cp\u003eThe mix knob provides full dry and wet operation, allowing for parallel processing. This is a great feature to have in a saturator since they tend to compress audio. Parallel processing allows the user to dial in the exact amount of saturation they want and provides full control over dynamics.\u003c\/p\u003e\r\n\u003cp\u003eA white led lights up when the distortion tube is being overdriven. Furthermore there is a bypass switch which switches the module out using relays for complete bypass.\u003c\/p\u003e\r\n\u003ch3 id=\"toc_1\"\u003eHIGH VOLTAGE\u003c\/h3\u003e\r\n\u003cp\u003ePlate voltage for the tubes is 240VDC, due to a DC-DC converter which generates the high voltage from the ±16V power supply of the API 500 format. This is needed for the best possible overdrive sound. This is unlike other designs which use the +48V supply for the plate voltage, which leads to a ‘starved plate’ sound. The +240VDC plate supply in this design allows for the best possible tube overdrive sound.\u003c\/p\u003e\r\n\u003cp\u003eNOS (‘New Old Stock’) tubes are used, meaning they are unused tubes manufactured in the 70s or 80s.\u003c\/p\u003e","brand":"Singular Audio","offers":[{"title":"Default Title","offer_id":44450885304423,"sku":"184551","price":769.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/1singular-tubedrve_184551_1.jpg?v=1787094954","url":"https:\/\/vintageking.com\/products\/singular-audio-tubedrve-stereo-500-tube-saturator","provider":"Vintage King","version":"1.0","type":"link"}
