Same first 6GW8 triode stage as Playmaster 101 Components Output Transformer A&R OT2632; 15W; 10k, 8k PP; 100/125/250/500 output. Opens in a new window or tab. jpg. 3. This design is based upon an ECL86 Amp design posted by Yves quite some time ago. The triode section in the ECL86/PCL86 is practically identical to a triode section of an ECC83/12AX7, so it has a high amplification factor of 100. Designed for the Mullard 3-3 amplifier but may be used in any single ended design with a valve having an output impedance of 5000 Ohms, such as an EL84. Power Transformer Ferguson PF170; 0,200,230,240V; 285-CT-285 80mA, 6V3 2A, 6V3 2A, 5V 2A. Regards, James. 2A * 0. if its not loaded up but I hope thats just my shoddy construction techniques and the use of both a dodgy old home made output Just a few little tweaks and the ECL82 could be used instead of the ECL86. org/static/2-3. Specially designed for use with Guitar Amplifiers, where a frequency response (aka bandwidth) of I replaced the output tubes in an ECL86 amp with PCL86, but in order to do this, I had to install a separate transformer to get the necessary heater voltage. Try a 20k ohm pot and reduce the resistance slowly. picked up a box of TV valves for €15 and 20% of them where pcl86 While the output impedance will be lower then a classic anode follower it will be far from ideal to drive the Zen + I/C. Part Number 210-6475 The 6GW8/ECL86/PCL86 was a stunning tube, I really don't know why modern tube manufacturers seemed to decide to remake the inferior 6BM8/ECL82 instead. Despite this, it's quite a nice (carefully designed) little amplifier despite very much being built to a price. Qty: Specifications Power 8 W Seller: primarywindings ️ (137) 100%, Location: Chichester, GB, Ships to: GB & many other countries, Item: 145336514027 EL84 Single ended 3. This is achieved by splitting the transformer windings up into several layers (or sections) which affects the coupling between input and output. Hashimoto A-305 2-pack Interstage Transformer Tango NC-20 Eqv 5kΩ 1 1 30mA; As I'm also from Ireland, I wondered what toroid would work as a substitute output transformer for these ECL86 valves - current OPT in Cadet is 8-9kohm. Grosso nucleo da 20 334607451996 The output of the selector switch is currently wired directly to the "V4 Section 1" grid. Those audio transformers are ideal for building amplifier projects based on Spud philoshophy, providing detailed sound and microdynamics that small transformers are not capable of. Baby Huey GB PCB - EL34 Build Thread I plan to build 2 Baby Huey stereo (BH) EL84 amplifiers, first to use a pair of these Toroidy outputs, second with a pair of Acrosound 310 output transformers (the best vintage EL84/8400 Ohm OT’s I know of). Record output has replaced phono input 1 so that I can select (3) line level inputs with the selector. Anything from Radionics that would suit? Would this require two connected in series? Any help greatly appreciated John ••• No special requirements needed. Will also function with: EL84 - 6V6 from 104548618 I had some tube type ECL86, it's basically an EL84 and 1/2 ECC83, which could then cut a Tube, I found a schematic from "Bogen" which has used this output stage. Joined 2007 The output of the first stage is fed to the triode section of the ECL86 which further amplifies the signal and applies this to the grid of the output section in the same valve which applies the The most well known amp with EF86 and 2x ECL86 was the Mullard 10-10, but it uses the ECL86 triodes in a longtail pair splitter. Controls: power. P. The The Stoetkit is a push pull design, which means you would need different output transformers and power transformer (one pair of extra ECL86 tubes), which are quite expensive. Greets: Tyimo Here is the Mullard: Attachments. . The maximum plate dissipation of the ECL86/PCL86 is highest (9 Watt, allowing a maximum output power of about 4 Watt). 162A). 0 bids · Time left 3d 18h left (Wed, 11:59 AM) or Best Offer +$26. With output transformers of 9k (Raa) ECL86 or 12a*7/EL84 schematics could be looked at. I chose this design because it was the simplest I could find last summer and I had already the power transformer. 00. (faulty coupling capacitors aside). Remember that pins are numbered clockwise when looking at them from under the chassis. Waiting to hear from anyone who can help Output amp is made with a couple ECL86.

Still 9-pin format, but it allows you to build a 13W version of an 18W PI and power stage with just two tubes. Toroidal Push-Pull output transformer for tubes: 2xECL86, 2xPCL86. der-trommler (4,742) 100%. So I swapped valves. After dismantling the transformer and unwinding it's primary, the wire was open in six different locations. Restoring 10w a channel jukebox stereo amp and one output transformer has half of the primary dead. Hammond 8 ohm output transformer. Do you mean that ECL86 is too powerful ? Or the schematic is a based on a poor concept ? Yes, the ECL85 and the ECL86 are not pin compatible. 6V and connect the filaments of two ECL86's Valve Amplifier Output transformer: 15W PUSH-PULL EL84 and ECL86 Valves OEP Audio transformer. Yvesm's ECL86 based precurser of Gingertubes "Baby Huey" might be a contender Personally I'm very fond of ECL82'S and think you should restore this amp and possibly exceed it's former glory. Now lets see of we can replace the driver stage with 6F5P triodes u=70 VS the u=100 of the 6GW8. I think for the ECL86 that I would lower the triode cathode cap value and the coupling cap value. Thanks for kind words, to be more specific I used cheapest Hammond PP-output transformers model-125D for output duty and two standard toroid power transformers 220V/12V 200 WATT connected with secondaries together to form one high voltage ( about 230VAC ) transformer. gain. ECL82 need handling with care. Hi-Fi typically require output transformers ECL86 Tungsram, ECL86 Tun NO, Trióde-Pentodes, NOS tubes, by Tungsram, The last one was ECL86 developed triode-pentode The ECL86 tube, specifically radio amplifier grades were developed 1962 , a PCL86, only the heating element of your space, they are designed for televisions European tube marking, according to the letter 6,3V-os E parallel, the P 300mA ecl86/6gw8 is an el84-like pentode (9w plate dissipation) and 12ax7-like triode on the same bottle. The real issue with single ended is the price of the output transformer. I have built a ECL86 and a 6F3 single ended amplifier and they both work fine. Low Budget Pat TTG -ECL86PP UL Push -Pull Output Transformer Toroidal Push-Pull output transformer for tubes 2xECL86, 2xPCL86 introduces benefits of toroidal cores to tube output. I am a looking for a schematic using some cheap output Hammond Manufacturing is a leading manufacturer of industrial enclosures, electronic enclosures, racks & rack cabinets, transformers, outlet strips and climate control products. (direct coupled or even with capacitor coupling to the speakers), which eliminates the output transformer and reduces cost, but it seems there is nothing around using small tubes D. Ik also have a little SE amp with ECL86 which came out of an old record player. But the general idea was to use a 70 volt speaker transformer as the output transformer, 120v to 240v transformer for high voltage and a a wall After a few years, the output transformer blew out; it's the only OT that blew in an amp I built. I know el84's are close but is there something closer? Cheers Rich . uk/g8hqp/ 2013-08-30 9: The original output transformers have a "Cabasse" embossed on the top of their U shield and there is a tap on the secondary which goes to a 22K+cap in parallel, which themselves go to the cathode of the triode driver. tiscali. You need test gear to do it properly. Add to basket. Solid bass performance required to 20Hz.
