Vintage Philips RH551 Pre-Amplifier. Rare item. This preamp was serviced approx one year ago by its previous owner and powers up nicely, but as Ive no means to test it Im selling as parts or not working. The item is in nice cosmetic condition with some occasional signs of wear. Any questions, please ask. Shipping: Shipping is registered and a tracking number will be provided on dispatch. If you are living outside Europe, please ask for a postage quotation.
