Description

I am selling this on an "AS IS" basis. It is listed as "For Parts only or does not work" The ONLY reason for listing in this category is to protect myself from the occasional unscrupulous buyer. However please read the following. I am an Electronic Technician. I replaced all six vacuum tubes with new old stock tubes. All potentiometers were cleaned with Caig Laboratories chemicals and are completely silent.
1.
CONTACTS
: I used Caig De-Oxit on every wafer contact. The wafers were not soaked. I only treated the contacts.
2. ELECTROLYTIC CAPACITORS - I changed all the electrolytic caps in the power supply and two other. I used slightly higher than original capacitance. I used
substantially
higher voltage ratings for longevity.
3. POTENTIOMETERS - I cleaned every pot with Caig MCL fluid. Each pot is dead silent.
4. VACUUM TUBES - ALL tubes have been replaced with new old stock tubes. Even though new, I still tested them to be sure they are perfect.
5. TUBE SOCKETS - Each socket was treated with Caig Labs DeOxit for perfect contact with tube pins.
6. SOLDERING WORK - Every single solder joint was inspected for proper soldering.
7. CONCENTRIC SHAFTS - Each shaft was lubricated and each turns freely.
8. The original owner had written "Tuner" and "Tape Deck" on the back. I tried to polish it out as best I could as shown.
I am listing this for parts only to prevent potential problems. YOUR opinion of a condition might be different than mine. What sounds great to me might sound horrible to you. I am being 100% clear and honest with what I have done and MY opinion of the condition. I will let you form your own opinion. I request that you view some of the feedbacks left for me. I do NOT sell junk. If it is not something I would use myself then it goes in the trash. I do not accept returns. Please ask any and all questions you might have before deciding to bid or purchase.
The performance of this preamp is
fantastic!
Zero hum or hiss and a great overall sound. Tons of versatility with the included separate channel volumes, bass, treble and adjustable loudness  and contour. Great tonal balance. Amazing high end detail/clarity, sweet mids and plenty of available bass (although it can be dialed back to taste easily). Just a wonderful all aro
und performer and a great introduction to tube preamps for less than half of what comparable ones sell for. I listened to this preamp while hooked up to dual Western Electric tube amps. They were amps using 300B tubes. The combo sounded incredible.
I must comment on what I found remarkable about this preamp. After I had completed the work I wanted to do I powered it up and played a few songs. I was blown away at the amount and quality of the BASS. To me it sounded incredibly rich and deep. I love a lot of bass and this preamp delivers what I like to hear with the tone controls at 12:00 noon. There is a lot of headroom. The hookup labels are dull and off white as shown. I did some really super looking brand new copies of the labels. They are plastic laminated and have 3M contact adhesive on the back ready to install over the originals IF this is something you want to do. I think the new labels look great. I used the original hardware when selecting new rubber feet. The new feet are much softer than the original tiny plastic feet. Original cracked feet are not included.
I will pack this preamp up extremely well. It will be GORILLA PROOF. I will leave the tubes in the sockets since they are very firmly being gripped by the socket and the shield. I do not know the number of the correct pilot bulb. The one that it came with was a bit dim to my liking. I will send it along with a 44 and a 47 in case you like those better.
INTERNATIONAL SALES: I ONLY ship to  a USA address. I will NOT ship outside of the USA. If you have a friend that will ship this to you then that can work for you. But please do not bit unless I can ship to a USA address.
I must repeat that I do not guarantee any particular type of sound or audio quality. Your taste different than mine. If you have any concern I suggest you read my feedbacks.
I will ship this item within 24 hours after ebay puts your payment into my bank account.
