Power Supply Capacitor Restoration Kit McIntosh MC-275 MC275 Tube Amplifier

Unlimited FREE Technical Support from our Degreed MSEE Tech Support Staff. Don't buy from anyone not qualified to back up the sale with real knowlegeable tech support.

 If you have purchased a vintage amplifier and have not changed the power supply capacitors, you have a time bomb on your hands.

Don't fool around with NOS capacitors unless you are looking for trouble.      

Please read the Disclaimer below before purchasing.

Although targeted for the MC275. this kit can also be used on other amplifiers as well. Our Power Supply Refurbishing Kit includes the following:

(A)

(4) 80/40/30/20 @525 V Twist Lock Cans CE Manufacturing USA Made, Brand New

Made in the USA, to Mallory's original specs, on Mallorys original machinery. 80 µF, 40 µf, 30 µF and 20 µF section, all rated at 525 VDC. 1-3/8" diameter x 3" tall Made in the USA by CE Manufacturing

You can replace the the (4) 100/30 uf cans in the MC275 with these (connect the 80/40/20 uf sections together to get increased capacitance of 140 uf, use the 30 uf as is).  These cans can be used anywhere the original cans of similar size are used. 

                                                                              OR (Depending on Availability)

(4) 100/100 @500V Twist Lock Cans CE Manufacturing USA Made, Brand New

Made in the USA, to Mallory's original specs, on Mallorys original machinery. 

• 2 sections - both 100 µF @ 500 VDC
• -10%, +50% tolerance
• 55° temperature rating
• 1-3/8" diameter x 4" tall

You can replace the (4) 100/30 uf cans in the MC275 with these directly. Connect the first 100 section to where the old went, and connect the second 100 section where the 30 section went. Very simple direct replacement connections.   These cans can be used anywhere the original cans of similar size are used.  

You can replace the (4) 100/30 uf cans in the MC275 with these directly.First connect each of 2 50/50 sections to make 100/100 uf. Thenas above, connect the first 100 section to where the old went, and connect the second 100 section where the 30 section went. Very simple direct replacement connections.   These cans can be used anywhere the original cans of similar size are used. 

Please note that any one of the options may be included in the kit.  The instructions cover each option. All three work great. 

(B)

(1) 22uf /250V  Electrolytic for replacing the Bias Filter Cpacitor.

(C)

(1) 1A 1000V PIV  Silicon Diode for replacing the Selinium rectifier

(E)

(1) 10K Trim Potentiometer (POT), for adjusting the bias voltage to the proper level (compensating for the lower silicon diode drop and adding more precision).  The POT is simply uses to determine the correct resistor value for your bias circuit, of which you then obtain and install. Its explained in the insatalliton tips.

(D)

Guide to installation - offer tips for easier installation- assumes you have the tools and technical knowledge and experience to do the work.

Most of these these items are sold separately in my Ebay Store as well.

Disclaimer:

Please note that this kit is not to be used by inexperienced users. There are high, potentially lethal voltages inside the MC275 and other tube amplifiers. If you don't know what you are doing, don't buy this kit OR contact us to schedule an installation for you. We provide installation services for all the parts we sell.

We do not take responsibility for personal injury, destroyed or broken amplifiers as a result of improper installation or lack of knowledge or tools. The guide we provide assumes you already have a knowledge of proper component installation techniques and the proper tools. This is not a trival task. The guide is by no means a detailed step by step installation guide.

Purchase more than (1) kit, or purchase other compnents and services from us and we combine shipping to save you money.

We also have Twist Lock can direct fit capacitors for a variety of other equipment such as the McIntosh C22, MX-110, Scott 299, Dynaco MKIII, and ST70 as well as for Guitar amplifiers. We also have the other Capacitor cans for the listed units available.

We offer complete power supply restoration kits for most amplifiers, preamps and tuners. An installation service for what we sell is available as well. We have more of these in our Ebay Store.

Tell us where you will be using these capacitors, and we will give you instructions on where and how to install them. Or, we can install them for you at a nominal charge + shipping. Your can email us or call us  to discuss your application and our installtion services. Our contact information is available in our EBay store.
