¿É¼ÇÁ¤º¸[(350853)PCB Booard][(193)DIY KITS][(350850)Finished Board]PRT11A Bile Tube PCB Board / DIY KITS / Finished Board PRE Preamplifier Board (Refer to US CARY CARY-AE1 Circuit) You have three options: ¡Ü PCB Board: 1pcs PCB Board ¡Ü DIY KITS: 1pcs DIY KITS ¡Ü Finished Board: 1pcs Finished and Tested Board Note ¡Ü DIY KITS and Finished Board Without transformer and electronic tube.
¡Ü This version will produce a microphone effect. When tapping on the PCB or the chassis, it will produce a relatively light vibration sound. It is necessary to do a good job of anti-vibration. New buyer should carefully choose this version of the product.
¡Ü The PRT11A uses AC lighting to supply the filament, one-point grounding, reasonable layout and wiring to minimize the mutual interference of the electronic tubes, and there is no bottom noise. Features: ¡Ü PRT11A bile preamp system reference-American Gary CARY-AE1 circuit, the circuit sound floor is significantly different from the traditional Marantz 7, Maijingtu C22, Hetian Mao, etc. It has the characteristics of fast speed, large dynamics, intermediate frequency density and charming charm.
¡Ü PRT11A uses Hitachi high-voltage filter capacitors, chemical high-voltage decoupling capacitors, Taiwan-made 3W 1% copper pin metal film resistors, gold-plated electron sockets, Sibi and MKP coupling capacitors, and has a good price-performance ratio. Parameter: ¡Ü 155 * 177 * 1.6mm ¡Ü FR4 Class A sheet ¡Ü This version is suitable for four 6SN7 (or 6N8P) large eight-pin tubes, 6SN7 is recommended. ¡Ü Voltage: High voltage 200-220VAC input, current not less than 30MA.
Filament: 3.15-0-3.15VAC input, not less than 3A.
We have matching transformers, if you need, you can buy directly£ºhttps://www.ÇØ¿Ü.com/item/4001046510449.html Regarding the plan to upgrade the mill: ¡Ü The quality of the electron tube has a great decisive effect. It is recommended to select high-level bile ducts within the budget. In addition, you can consider upgrading and replacing the coupling capacitor, such as MCAP, etc. Package include: PCB Board / DIY KITS /Finished Board for PRT11A Bile Tube PRE Preamplifier Board
