Transformers double clutch with

Pair of 30 kOhms to 150 + 150 Ohms (600 Ohms unbalanced) Bartolucci line output transformers. They are ideal for tube preamplifier but could also be used as low output impedance interstage (as example, for 805 tube that needs huge grid current). These are made of potted double C cores. Primary resistance: 1260 Ohms Each secondary's resistance: 44 Ohms Specs mention 240 H primary inductance and 15 mA DC current. I measured 372 H on 50 Hz line voltage. Dimensions: 103 x 89 x 92 mm height Weight of each: 2050 g They were used and have some minor scratches that you can see on pictures but condition is very good. Outside Europe: 54,65 Euros (with tracking). Please contact me for express shipping / insurance.   Pour la France, jusqu'au 11 mai, envoi standard par UPS (livraison estimée: 24h).

For sale, A pair ofexceptional mono blocks, 250 Watts of roaring EL34s! Secondhand, manufactured in 2021, imported in September 2023 from Norway (storeinvoice and import VAT will be provided for the sale). Impeccable condition andoperation! Like new. This is the latest version, with ultra-linear mode insteadof tetrode, in addition to triode mode, and revised transformers for betterbass! Factorysorted and matched tubes by Manley, documentation and multimeter provided (forsetting Bias!). Per block, 10 * EL Tung sol 2 * 12bh7 EH, and a GE 5stars12at7. I have theoriginal double boxes, shipping could be arranged, after discussion andquotation. (35Kg for each baby...). Theseblocks are purely fantastic, both in their devastating look and their sound,250W under 4 and 8 ohms, in ultra-linear, 100W under 4 and 8 ohms in triode(actually nearly 180w measured by Stereophile.... at 1% distortion in triode). Theseblocks will be able to power large speakers (Manley refines its amplifiers onTannoy 38...), at indecent sound levels; in an incredible silence for blocks ofthis caliber, and a refinement to make other achievements pale with jealousy. Theamplifier has a soft-start (preheating) and a standby, to extend the lifespanof the tubes, which are ultimately not mistreated considering the deliveredpower... Behind thefront plate, each tube has its own idle current adjustment. This crucialadjustment allows you to respect the lifespan of your tubes, and not to beforced to change all the tubes at once if one were to weaken. The tubesinstalled in the blocks still have many days ahead of them, as the amplifiersmainly serve 2-3 hours on Sunday afternoons (and some Saturday eveningstoo...). Delivery is possible; but please ask for a quote first En savoir plus

Hello I offer for sale my high-end amplifier Exposure XXVIII (28)  It is an amplification that is characterized by a lot of punch, and softness, beautiful bass, midrange and treble very just right  A very serious power supply which allows to masterfully hold difficult speakers and requiring power.  It is the power supply that makes the power not the watts... It goes down well with very nice stamps and nice aeration.

Welcome! For sale is Electro-Voice CPS4.10 apmlifier with 4 channels of each nominal output is 1000W. MSRP: 3200 US$ Amplifier was never used (just tested before i made this listing) and it is 100% operational. See more technical details below. Shipping We will ship to any location worldwide. Please send us message for shipping cost to your location. All customs fees are not included in the international shipping costs. Buyer is responsible for all customs fees.  Please contact us if you have any question regarding this item.  CPS4.10 This four-channel CPS amplifier from Electro-Voice features groundbreaking Class-D technology for maximum amp efficiency and minimized heat dissipation in 19-inch racks. Each channel individually provides transformerless, switchable output characteristics, which enable specific channels to achieve maximum drive. Power into 2 Ohms, 4 Ohms, 70V, or 100V line – no transformers are required. In Hi-Z operation (70V or 100V), a 50 Hz high-pass filter (HPF) provides protection against loudspeaker transformer saturation. Additionally, amplifier channels can be bridged in pairs for double output power. Each contractor-friendly, multi-channel CPS amplifier also features Phoenix-type connectors for inputs and outputs, pre-programmable power-on delay, easy power-on remote via contact closure, and rear level controls. A module slot for the RCM-810 remote control module provides control network functionality, allowing for remote system diagnostics and control via IRIS-Net software. In addition, using the RCM-810’s Variable Load Drive feature can tailor the amplifier’s output power to match every load from 2 Ohms up to 10 Ohms in steps of 0.1 Ohms.
