Title: ZMA for sale. All the Bells and Whistles Post by Carlsbad on 06/27/23 at 03:42:13 For sale is my ZMA with 25th Anniversary Mods and XLR + RCA inputs. Additionally this amp has had switches professionally installed to swap between RCA and XLR inputs (otherwise you have to swap cables). While working on the amp the technician upgraded the signal wire to Mundorf silver/gold/copper. I also had him change out the RCA inputs to KLEI Perfect Harmony silver. There are photos in the linked google drive album of the swtiches (tiny, one per channel, just in front of output transformers) and the bias adjustment knob extensions. I also am a machinist so I made myself a pair of brass bias knob extensions that make adjusting the bias much easier. see photos. I thought about offering to make and sell these but I have so much time invested in making them I'd have to charge too much. This amp has the best bias adjust system of any amp out there. Steve really did a great job creating this. the 4 meters allow you to tune the bias perfectly for each tube. Specifications: World Voltage compatibility 50/60Hz INPUT TUBE Compatibility: 6N23P, 6922, 6N1P, 6DJ8, 7DJ8 OUTPUT TUBE Compatibility: EL34, 6CA7, KT77, KT66, 7027, 5881, 6L6G INPUTS: OPTIONAL TRANSFORMER BALANCED XLR INPUTS (Included) INPUTS: SINGLE-ENDED RCA INPUT OUTPUTS: 4 & 8, or 8 & 16 OHM SPEAKERS IDLE CURRENT: 40~70 MILS PER OUTPUT TUBE - ADJUSTABLE HIGH B+ VOLTAGE: 410 VDC WITH LOAD INPUT IMPEDANCE: 100 K OHMS INPUT SENSITIVITY: FULL POWER @ 2.0 VOLTS ON RCA INPUT POWER INTO 4 , 8 or 16 OHMS: 38 WATTS PER CHANNEL NOISE: -90dB PRECISION CURRENT METERS 0 to 100 MA WINDOWED BIAS CONTROL to ADJ OUTPUT TUBES DYNAMIC BIAS BALANCE CONTROL FOR PERFECT MATCHING of EVEN UNMATCHED TUBES COPPER FOIL MIFLEX - SIGNAL CAPACITORS OPTIONAL 20 POS STEPPED ATTENUATOR w/ GOLD CONTACTS for INPUT LEVEL (GAIN) CONTROL (this amp has the stepped attenuator) 3300 UF 500V LABORATORY GRADE POWER SUPPLY CAPS GOLD TEFLON INPUT JACKS (upgraded to KLEI in this amp) RECTIFICATION: ULTRA FAST RECOVERY 3 AMP 1000V MACHINED STEEL CHASSIS with POWDER COAT FINISH HI-GRADE FUSED IEC CONNECTOR for REMOVABLE POWER CORD SOFT START- NO STANDBY NEEDED SHIPS WITH: PREMIUM GRADE KT66 OUTPUT TUBES PREMIUM GRADE 6N1P-EV INPUT TUBES (I like 6N23P better, included) OA3/VR75 REGULATOR TUBES SIZE: 19-1/8" WIDE x 13-3/4" DEEP x 8-3/4" HIGH NET WEIGHT: 43 lbs. I have so many great things to say about this amp but I'll stop now. I'm selling becasuse I have a custome made amp on order that will be delivered in a month. I'm sitting listening to this amp as I write the listing and wonder if I'm making a mistake. anyone in So cal or traveling to So Cal is welcome to come listen to it. Comes with KT66 main tubes (original equipment) and some others. I'll include the 807s with adapters shown in one photo and another set of tubes, perhaps Mullard EL34s. I'll also include a set of Russian 6P3S which are some of my favorite tubes in this amp. They also have the most blue glow at night. I have 6N23P input tubes in it and will include a spare pair of input tubes. I'll include a spare pair of OA3 regulator tubes. I upgraded the knobs to some pretty cool choices. see photos. I'll include the white chicken head knobs as well. Ships in it's own pelican case and I'll ship the tubes in a seperate priority mail box. I have the original power cord. I think it is unused. It will be included. I recommend an upgrade and will be glad to help you pick one or can include a basic upgrade cord for $75. List price is $7544 not counting the upgrades I had done or the extra tubes, etc $6750 shipped. Ships in custom wheeled pelican case. I am listing this for a week or two only on the Decware forum. after that I'll list it on US Audiomart. Photos on my google drive: https://photos.app.goo.gl/9nqqqFVTHSgaiqYeA |
