I feel I need to explain the batteryless mod a bit further. There is a 28 pin memory chip in the units that holds the user settings (typically Newman settings). This chip needs a battery to hold its memory when power is off. I remove the battery and replace the 28 pin chip with a non-volatile chip. It will hold your user settings with no need for a battery to back it up. This elimates the battery in your unit forever.

I am seeing more and more units coming in with battery damage and obvious problems in operation. I am limited to the repairs I can do on a Profex 2/Bassfex. I do not repair Tubefex, Transtubefex or others, I just do the battery less mods to them. If your unit needs further repair I will be glad to send it over to Mike Brown and the boys for expert repair! I have done so for several already. I supply them your billing information and they take care of it from there.

I can get your units out usually the day after they arrive. It is easiest for me to repair and ship back and then bill you via email. No need to send payment in advance.

The price has now incresaed 50 percent due to the fact theses are the last of the chips on the market. I had to order 100 to even get that good of a price! My distributor is out, ZMD will not be making any more NVSRAM chips and the last of them are in the hands of one or maybe two (one still uncorfirmed) surplus parts houses.

Effective immediately my prices are increasing to cover the cost:

Option 1:

$45.00 for the chip, reload your settings or I can reload from my collection, repackage and ship. I have a nice combo of Jeff Newman and Jeff Peterson settings I can load. You do not lose any Newman settings, just the some that were duplicated.

Option 2:

$50.00 for the Burr Brown chip upgrade, Profex 2 and Bassfex only. The result is a lot less background noise and a sweeter sound. Four chips are replaced with this mod.

Option 3:

Total is $90.00 for both of the above mods for Profex 2/Bassfex.

Shipping charges are additional . I will send an invoice in Excel format and include a copy with your upgraded unit.

I am adding a $2.50 handling charge to cover the cost of shipping tape, running these items over to the post office on occasion, bubble wrap (some units are requiring additional packing), shop items (Q-tips, denatured alcohol and such).

Here are other things I can do for you:

1-I can replace broken pots for $15.00 each (volume on the front or rear only for Profex 2 or Bassfex and only at this price if the unit is sent for the the Burr Brown and/or the battery-less mod), also power supply input jacks for same (have only seen 2 bad ones in all the years I have worked on the units). I keep the pots and jacks in stock.

2-Knobs are $3.50 additional.

3- I can also replace the battery in your cache card, if needed and reload the settings to it for $5.00.

4-Output mod to accommodate a power amp/rack system, doubles output voltage! This is a $5.00 mod as long as you are doing the battery-less memory chip for Profex 2 /Bassfex only!

5-Power supply (wall wart) for Profex 2/Bassfex at $15.00 and shipping. I have a limited supply of Basler 16.5VAC transformers with the correct 2.1mm power cord. This unique transformer also has screw terminals for easy cord repair or replacement. I have used these in my shop and also sold many in the last few years.

-I do not need your power supply sent with the item, I have several here already.

Pack to protect the racks ears! They bend easy in shipment. Try to pack so the item does not shift. Items packed in peanuts will move all around and bump the ears. I have seen many damaged this way. Wrap in bubble wrap for best results.

Personal check is fine. Postal money order works, too!
If you use PayPal I must add about 3 percent to cover the fees they charge me.

They seem to get the worst of it, as the battery end is so near a voltage rail! Only slight leakage is needed for this to occur.

Bottom line, check and clean the battery before you get this problem (blown components and lots of smoke).

If anyone had a dead/non-repairable Profex 2 or Bassfex for sale let me know. I could use a few for spare parts, as some of the parts are no longer available.

Below is a link to pictures of some damaged units I have repaired. This is typical from excessive battery leakage. All batteries will eventually leak on these units!

Just wanted to drop a few lines your way about Ken. He does a GREAT job at improving
an already great unit the Pro-fex.

I bought a unit from ken several months ago and needless to say I have had NO PROBLEMS whatever with it.

Thanks Ken for your untiring contribution to the steel guitar industry..

Are you going to be at Saluda? Are you going to have a table there? If not, how will I be able to find you? I plan on being there Sunday and bring my profex for the bat and brown mods.

Thanks to all who have ordered chips or sent units for repair.

Thanks again for all the business this year! I have had a great time getting the units updated and met a lot of new folks along the way.

Plenty of battery chips still in stock at this time. There are 9 Profex units supposed to be on the way now for upgrade.
Should be in good shape on the battery eliminator memory chips. I am running low on the Burr Brown chips and will re-order soon, if there seems to be more interest coming. It only takes a week to get them here from my supplier. I have to order at least 100 at a time to offer the low price on that upgrade! Let me know if you have a unit coming and are interest in the Burr Brown chips, so I can place an order soon.

Hopefully yours has been done or will get done before this happens. I believe that all these batteries will leak in time. Unfortunately I am seeing more and more coming in with damage.

While I make every effort to get the unit up and running, I can't spend hours on them. If it looks as if I can't repair it in a timely manner, then I will call you and offer the option to send it from here to Peavey for repair.

Ouch! I did a lot of research and found 5000 in Chine. I really did not want to import them.

I just located a parts house, not a distribitor with 5000 in Florida. I got 200 ordered and on the way. It takes 4 per unit for the upgrade. That will cover 50 Profex 2 or Bassfex units!

I only have 16 left in stock today, so that will cover 4 more units. I should have stock next week.

Please remember to include your name, address and details of mods you need. I get one every now and then from a shipping center and no personal info! It can takes hours to track down a phone number and email! I had one unit that was here over 6 weeks before I could locate the owner. I keep track of every email I get, but sometimes that can so sideways as well!

I got in a shipment of 52 after the shown and am down to 38 already. I still have plenty of the Burr Brown chips, last shipment was 200. Over half are gone at this time.

Thanks again to all who have had this work done!

Or is that something you don't provide? I wouldn't mind sending you the unit but I think it would much easier for me to do it. I wouldn't mind paying the full rerplacement price if you would give me instructions on the steps of replacing the chip and removing the battery.

Now if this is not something you like to do that's no problem I can remove the chassis and send it to you but I'd rather not.

I do not recommend anyone doing a chip change unless they are comfortable and familiar with changing IC chips out and also has basic understanding of static protection.
