Here is a fully restored pair of Heathkit w5m mono-blocks, with Peerless 16309 output transformers with nickle cores INCLUDED are a pair of Cages (not shown) these are very clean but they are un-restored with the original paint that show some signs of wear
These sound excellent. and have been lovingly restored from the ground up
I have used matched components during the rebuild and upgrade
Also Note: that the scale for the balance voltage is MV (mili-volts) and ideal is 0 volts, with the meter set to volts it reads “0″
all parts of the chassis and have been sand blasted and painted with primer and automotive paint that was color matched with the same color as the originals(clear coated)
the power transformers and choke have also been sand blasted primed and painted with black automotive paint (clear coated)
Output transformer #1 has been painted with hamertone paint to match the original
Output transformer #2 has the original paint and decal, it matches closely to the other but the origianl paint was in perfect condition
these have SDI Labs Cap Board installed with the original can caps in place for looks (they have been clear coated with automotive paint)
NOTE: the chassis do not have lettering and the rubber feet are slightly miss-matched between the amps.
aside from the feet they are they are virtually identical
NEW Power Switches
all new parts – Metal film or metal oxide resistors that have been hand matched
IEC power cord connector
Gold Plated input jack
lab grade Balance inputs
gold plated banana plug speaker outputs (these have been tied to the 8ohm taps – the 4 and 16ohm taps are still available under the chassis)
New Solen “fast caps” through out
Silver wire or point to point in the signal path -
Cloth covered wire in power supply
New filter caps and SDI Labs cap board
New tube sockets (9pin)
NOS tube sockets (octal)
:hi wattage ziener diode on the B+ to drop the voltage to 1957 levels (1957 line voltage was 110v modern voltage is about 115 to 117)
Thirmisters to slow the turn-on current to allow for the power output tubes to warm up before the B+ is applied
Higher wattage resistors in parts of the power supply to help with reliability
IEC Power Cord Connector
Gold Plated RCA Input Jack
Gold Plated Banana Plug Jacks
New kt66 tubes (JJ) they are matched pairs and as a quad between amps
NOS 5R4 Tubes – RCA Brown Base – Matched electronically – slightly different physically
12au7 matched various brands currently I am using RCA’s, I will ship with 4 closely matched NOS 12au7 tubes (I will re-test them and make sure they are still matched and sound great
I have been listening to these amps for at least 5 or 6 weeks and they sound great! all then need is a new home.
I will ship them in 2 boxes and they will be very well packed. – keep in mind that these amps weigh about 30 pounds each
I dislike having to post anything negative. But I feel it’s my duty to warn consumers when a business goes bad!
I’m speaking here about a company called Welborne Labs, http://welbornelabs.com/ I had ordered some parts and products from them over a month ago and promptly paid on my credit card. Fast forward to today. I have made dozens off attempts to contact them via email and by telephone on the status of my paid for order. To date I have received no replies. I do know they are receiving my emails, this is verified. They continue to send updated “specials” on their newsletter. So I would assume they are alive and well?. Are they just scamming unsuspecting people into making orders and paying for them with the intent to not ship any product?.. I do not know.. But I would say stay away from them. I will keep you all informed if I do hear from them and any resolution is forthcoming. I’m having my credit card company revese my charges at this time
Some updating is in process at the “Tubeology” HQ’s….. more later with pictures!
This summers projects in the works, I’m open for a deposit on a McIntosh MC240 that is now in the process of restoration. This unit will be MINT, a “10″ it gets a full new chrome chassis along with a total electronics rebuild and a warranty. $ 1,000 deposit secures it. The total price plus shipping is $ 5300.00
Next we have a Marantz 8B. This unit will clean up and be near a 9.5 in cosmetics, electronics will be rebuilt. The deposit on this one is $ 1,000 and the total price plus shipping is $ 3250
OK, I have more.. a few Fisher 500b/c’s and 800′s. An Eico HF-81, A McIntosh c20, yes C20! price yet TBD. But it will get a full face lift and all electronics rebuilt. Lot’s more stay tuned.
With vacation season upon me, times vary for finish of projects, If you are considering having me repair/rebuild any components for you contact me ASAP so I can get you in the “Q”
Some happenings at CTA (Classic Tube Audio) I’m sure by now many of you have noted the new logo (I’m very pleased with it) and some changes to the look of the web site (more in the works). During this visible change, behind the scenes we have been expanding our inventory of parts. Several advantages we have, buying in larger quantities and saving money. This allows us to control some costs and our customers reap the savings. The other issue is faster turnaround time and we now can precision match and select for match pairs/quads and more. This applies to Capacitors, Resistors, Tubes. We also are adding to our “premium” upgrade and select “Tubeology” line of offerings. Later this summer the “shop” will be adding more work area space and dedicated “burn in” for QC of serviced components. This is one area I’m really proud of our tradition. A quick explanation of our burn in process. Every finished unit gets a minimum of 10 hours of run time. This really helps us with making sure all voltages remain stable, bias drift is minimised, we apply both audio frequency sweeps during the burn in along with playing music extensively though the units. Yes, we actually listen to each and every unit before it goes out! This process has kept any issues to near zero once the component arrives back to you..
I must give a sincere Thank You! to the hundreds of customers over the years, you are the ones that have allowed us to grow. I’m very excited, the future is bright. Real Audio Glows in the Dark!
